Today cricket is one of the most popular games in India and abroad. So it is felt that modern technology can be utilized to develop a cricket ball throwing machine with variable speed, swing and spin for the benefit of practicing batsman. The cricket ball throwing machine is to provide accurate and consistent batting practice for players of all standards like professional cricketers, amateur cricketers and club level cricketers. From the experience of our college cricket team players, we realized that the lack of practice with consistent bowling styles was costing them losses at university matches. Also, the purchase of a 'Cricket Bowling Machine' was hindered due to its 'high cost'.The objective of the current work is to design and develop an improved cricket bowling machine, which is capable to throw balls at various speeds, in predetermined line and length. The machine also will be able to provide spin deliveries by adjusting the orientation of the ball delivery system. Expected Outcomes of the project: • To develop a cost effective (economic), compact ball throwing machine. • To deliver the balls at around 110 kmph. • To provide provision for using different sized balls. • To offer greater mobility i.e. 3 axes of freedom system which should be able to pitch the ball at the right place and spin in the required direction.

Project Guide: Mr Noel Deepak Shiri, Assistant Professor, Department of Mechanical Engineering Abstract: Waste is now a global problem, and one that must be addressed in order to solve the world's resource and energy challenges. Plastics are made from limited resources such as petroleum, and huge advances are being made in the development of technologies to recycle plastic waste among other resources. Plastic has become prevalent because it is inexpensive and it can be engineered with a wide range of properties. Plastics constitute approximately 3-7% of municipal waste. Presently, the municipal garbage disposal departments bury the plastics along with the other materials in landfill without recognizing its ill effects. In India, there are three common ways of getting rid of plastics - by dumping them in landfills, by burning them in incinerators and by littering them. In the case of littering, plastic wastes fail to reach landfills or incinerators. Extrusion process plays a prominent part in recycling waste plastic into useful products. Our projects goal is to reduce the waste that is rising in the present world and to achieve this goal; a system is designed incorporating a plastic extruder. We undertook this project in order to use waste plastic and convert it into building materials with the help of an extruder, thereby reducing the plastic waste which is key factor for the environmental pollution. This method effectively converts waste plastic into useful building materials like building bricks, floor interlocks, roof tiles, railway sleepers, paving slabs and retaining blocks etc., using either single plastic waste material or a mixture of different plastic wastes and also with Plastic-Rubber composite materials. And this setup can effectively reduce the environmental pollution and further decrease the problem of waste plastics in the society. For the future, this work can be improved in design and production by implementing additional systems such as a mixer, fume purifying systems and insulation system.

Project Guide: Mr Anil Melwyn Rego, Asst. Prof., Department of Mechanical Engineering This Project is sponsored by Karnataka State Council for Science and Technology (KSCST). Abstract: Sustainability of available water resource in many reasons is now a dominant issue. This problem is quietly related to poor water allocation, inefficient use, and lack of adequate and integrated water management. Today, ecotourism is growing rapidly. For hotels, Wastewater Treatment and Water management are the two most important operational criteria. This translates to controlling discharge into the environment while creating a world-class eco-friendly facility. By doing this, hotels aim at lowering their operational and running costs. In this regard a few tourism spots in and around Mangalore were identified to understand the need of water management system. Mangalore is the land of beaches and the problem of water management have strike the beach resorts also. The resorts are facing many problems in this area. First to tackle the waste water. Then to handle the salinity level of water which shoots up during the summer season. So the need for effective water management system in beach resorts is realized. In the current project the real situation is modeled into a scaled prototype using respective mechanical and electro mechanical subsystems. Then they are interconnected and monitored using LabVIEW. The system uses the LabVIEW software to automate the process of water pumping in the system and has the ability to detect the level of water in different tanks, switch on/off the pump accordingly and the status will be visible on a display. Main Features: • Cost effective water management system. • The system facilitates water supply to any point in the area under consideration. • Corrosion of components will be prevented since saline water will not be added to the system. • Different parameters of water such as water level, pH, salinity and temperature, can be monitored and logged for future reference or study. • Manual operation of system in case of failure in electronic subsystem. • Complete integration of all subsystems for cross communication.

Project Guide: Sharun Mendonca, Department of Mechanical Engineering This Project is sponsored by Karnataka State Council for Science and Technology (KSCST). Brief Write-up on the Project: Currently wind power is experiencing an enormous boom. Most people associate wind power only with conventional wind turbines, but research has led to a yet new source of renewable energy: kite power. The assignment therefore was to: ‘design a small scale kite power demonstrator’. The work here will include a way of adopting two kites to harness power by alternately changing their angle of attack. The power lines will run the generator to generate electricity. The kite's angle of attack will be changed in such a way that the force in one of the kite will be higher which will pull the power line to its side rotating the turbine. Then the AoA (Angle of attack) will be reversed so that it gives a "churning effect". Brake lines will be used to control AoA. Main Features: • Renewable source of Energy. • No pollution. • Cheap compared to Windmills. • Can be used in small-medium scale. • It can be Automated.

Project Guide: Mr Rolvin Sunil D’Silva, Assistant professor, Department of Mechanical Engineering Abstract: The usage of plastic has increased drastically in past few yearsall over the globe. The reason behind this is that the plastic articles are quiet easier to manufacture, handle and reliable to use. The plastic goods manufacturing industries are striving hard to produce cost effective and good quality products at large scale which makes use of hydraulically operated machines.Thesmall scale and medium scale industriescannot afford these machines because of their high cost. The project work deals with the design and fabrication of Semi-automaticplastic injectionmoulding machine on a low budget, which can be operated manually with less effort.The design, construction and testing of the injection moulding machine has been successfully accomplished. It is observed and concluded that the practicability and efficiency of the machine depends on strict compliance with the operational procedures of the machine. This work is designed and constructed for the small-scale production of small plastic articles. Hence, it can be recommended for small-scale investors who are willing to produce small plastic articles such as key holders, clothes pegs, flat rulers, bottle covers/caps. In this machine hydraulic jack and springs are used for plunger movement and automatic opening of die. This machine is simpler in design with low operating cost which can be used in small scale industries to manufacture small plastic articles Main Features: • It is mainly designed for small scale industries to produce small plastic components or articles. • It requires very less manual force as it is operated using hydraulic jacks, hence easy to operate. • Due to the use of springs, retraction of the die and plunger takes place automatically on releasing the pressure. • It can produce four components per minute, hence the cycle time is less and production is faster compared to the conventional hand moulding machine.

Project Guide: Rudolf Charles D’Souza, Senior Lecturer, Department of Mechanical Engineering Abstract: Safety is of prime importance in day to day life. There are many instances of accidents taking place which may cause human injuries and problems to the machine. Accidently touching the rotating cutter, clothing getting caught by the spinning rotor, intervention of external objects during operation are some of the examples affecting both human life and machinery. This project is intended to prevent such accidents by disengaging the power transmission whenever there is any possibility of accident. The solution for the problem is obtained by making use of a braking system and an electronic circuit containing a proximity sensor. Whenever there is an obstruction in the proximity of the sensor two signals get generated. One will disengage the clutch cutting off the power transmission. The other signal will trigger the actuator which will push the external contracting brake against the rotating shaft .Both the actions occur simultaneously resulting in instant stopping of the rotating member. Features: • The safety mechanism ensures the worker’s safety. It is also seen that the sudden stop doesn’t affect the machine components, thereby not compromising with its service life. • It can be installed in any machine with rotary motion. • With suitable modifications it can be incorporated even in the machines with other types of motion.

Project Guide: Mr Prathviraj H, Assistant Professor, Department of Mechanical Engineering Abstract: In the modern world the depletion of non-renewable sources of energy has led to the development in methods of harnessing non-conventional energy sources. There are various non-conventional sources of which solar energy is the most plentiful energy source for earth. According to research conducted by various experts, solar energy falls on the surface of the earth at a rate of 120×〖10〗^15watts. This means all the solar energy received from the sun in one day can satisfy the whole world’s demand for more than 20 years! Thus harnessing this energy will be extremely helpful in improving the quality of life for many people around the world. There are mainly two methods of harnessing solar energy. They are Photovoltaic method and Concentrated Solar Power. In this project Concentrated Solar Power technology is considered for utilizing solar energy. Here a parabolic dish type solar collector is used to collect solar energy and concentrate it at a single point (focal point). A thermally insulated solar receiver is fixed at this point which is filled with water. The receiver absorbs the concentrated solar energy and the heat developed is utilized to convert the water into steam. This steam is sent to the steam turbine which rotates the shaft. This shaft rotates the dynamo, thus producing the power output. Initially the solar receiver is fed with 2liters of water, which is then fixed on the Solar Parabolic Dish. The Dish is aligned with the sun’s direction (focal point) with the help of a manual tracking mechanism. The boiler/receiver is allowed to boil for a period of 50 to 60 minutes. At this point a pressure of 4kg/cm^2 is attained at the pressure gauge. The Flow control valve is opened and the steam is let to flow across the insulated copper tube into the nozzle of the steam turbine. This steam is then sent as an inlet to the steam turbine which in turn rotates the shaft. The end of the shaft which has a dynamo fixed on to it gives the output voltage. Temperature and pressure variation was noted. Various calculation related to zenith angle, solar radiation, steam calculations, mass flow rate usinf orifice method,theoritical power output of the steam etc was calculated. By the end of this project we are able to concentrate solar energy at the focal point of the parabolic dish solar collector and achieve an average maximum temperature of 210c at the focal point. Based on the tests conducted in the month of April and May, an average steam pressure of 4kg/〖cm〗^2was obtained in nearly 70 minutes in the time interval between 11.00am to 2.00pm and mass flow rates was found. The steam pressure obtained is used to run a steam turbine and produce output. Errors in mirror alignment in parabolic dish were observed. Automatic tracking mechanism has not been incorporated. There is no closed loop setup for water re-circulation. Also various frictional losses have been observed in the system. If these limitations are overcome a better system can be developed. Features: To design and fabricate an efficient solar thermal power generation system at minimum cost To use a parabolic dish collector for producing steam To introduce a steam turbine coupled to a generator to measure output power To measure and calculate various properties of steam like pressure, temperature, collector efficiency, mass flow rate, theoretical power output of the steam Heat obtained through concentrating solar energy can be used for various application It uses renewable energy to produce power, hence can be used as a alternative form producing power

Project Guide: Binu K.G., Associate Professor, Department of Mechanical Engineering Abstract: The applicability of TiO2 based nano-oil as a coolant to reduce the structural temperature of a pulse jet engine in studied. A test rig of a pulse jet engine operating on LPG is tuned for sustained operation. A cooling system was designed, and installed on the engine with provision to measure temperature at four structural points. Stable dispersions of TiO2 nanoparticles in engine oil was obtained using 2-step approach. Experimental results reveal a successful decrease of 60% in maximum temperature with the use of 0.001 volume fraction of TiO2 nano-oil in comparison with non-coolant operation for a duration of 3 minutes. Salient features: • The excessive heat generated during the operation of pulse jet engines limits is application in long-duration operations. This study is an attempt to develop a cooling system for the pulse jet engine operating on nanofluids to significantly decrease the engine temperature. • The solution for the identified problem involved the design and fabrication of metal jacket-based cooling system and its application in pulse jet engines using engine oil and nanoparticles dispersions in engine oil as coolant to decrease the excessive heat generation. • The engine was tuned to obtain sustained firing by improving the air flow into the engine. The experimentation involved operation of the cooling system in the pulse jet engine with plain engine oil and TiO2 nanoparticles dispersions in engine oil. The temperature generated in the engine for a fixed duration of engine operation was observed and monitored. • On successful experimentation of the cooling system with plain oil, it was realized that the overall engine casing temperature was reduced by ~ 40% and its usability time increased. We could run the engine for a longer duration with minimal temperature spikes, reducing any damage to the casing due to high temperature. • Similar experiments were carried out using TiO2 nanoparticle dispersions in engine oil, at very small volume fraction of 0.001, and the results revealed a further decrease of 20% in maximum case temperature in comparison with plain engine oil. Future Scope • Further research can be done on pulse jet engines to reduce engine noise, reduce fuel consumption and to utilize the heat liberated for power generation purposes. New designs can be developed on basis of reducing overall size and weight of the engine. • The nano-oil parameters such as, nature of nanoparticles, particle size, volume fraction, formulation procedure, sonication duration, and volume flow rate needs to be optimized.

Project Guide: Mr Ravikantha Prabhu, Assistant Professor, Department of Mechanical Engineering This work is mainly focused on development and evaluation ofphysical, mechanical, tribological and hydrophilic behavior of epoxy based composites filled with different percentage of coconut fibers. The coconut fiber (CF 0-15wt% in steps of 5 wt %) were reinforced in epoxy resin to prepare fiber reinforced composites of different composition. Composites panels were made by hand lay-up process and the properties are testedas per ASTM standards. • Density (ASTM D792) is found that by the addition of coconut fiber increased the density of the composite. This is because of highly dense coconut fibers. • For tensile (ASTM D3039), we found that the 10% coconut fiber composite has the maximum strength and it was found to reduce as we increase the percentage of coconut fiber. • For hydrophilic, the water absorption curve illustrates that the minimum water absorption is for the composite prepared with 5% volume fraction. It is also observed that an increase of coconut fiber volume the corresponding water absorption percentage increases. • Abrasive wear test(ASTM G99) among the coconut fiber composites the composite having 15% of coconut fiber was found to have the minimum wear loss. • Dry sliding wear test(ASTM G99) for 10% and 15% coconut fiber composite the wear loss was found to reduce. But for 20% coconut fiber composite the wear loss slightly increases.
