Item Analysis of heat exchanger performance using wind tunnel test rig facility(AIKTC, 2020-05) Shaikh, Rizwan; Albuquerque, Farhan (16ME05); Ansari, Rehan (16ME12); Chaurasiya, Sunny (16ME15); Nadar, Venkatesh (16ME50)In this study performance evaluation and testing of the heat exchanger (radiator) are done using wind tunnel test rig facility because all internal combustion engines produce heat as a byproduct of combustion of fuel and friction of moving parts. This heat can reach temperatures up to 1925°C (3500°F) and can cause catastrophic damage to the engine components. Furthermore, it can have negative effects on the engine such as reduction in engine performance and shortening of engine’s service life, therefore cooling systems must be accurately designed, tested, operated and maintained for optimum engine life and smooth operation.Item 'ANSYS' analysis of pressure vessel(AIKTC, 2018-05) Shaikh, Rizwan; Ansari, Nabil Ahmed T.(14ME03); Azharuddin, Hamiduddin(14ME07); Khan, Mohd. Hatim(14ME22); Upadhe, Salman R.(14ME59)Saddles are used to support the horizontal pressure vessels such as boiler drums or tanks. Since saddle is an integral part of the vessel, it should be designed in such a way that it can withstand the pressure vessel load along with the operating weight. High pressure is developed in pressure vessel so pressure vessel has to withstand several forces developed due to internal pressure and external forces such as wind. Horizontal pressure vessel with saddle support is designed to store H2 operating at a pressure of 4.4MPa and analyzed by using FEA software ANSYS. Saddle has to carry stress pressure inside the vessel. Apart from that stresses due to self-weight and other atmospheric condition. Considering this theory, the focus is on a structural analysis and optimization of weight and improvement in stresses of saddle support which in turn result in reduction in cost. The results obtained shows that the saddle support design is safe for the given loading conditions and provides the theoretical basis for further optimization.Item Automatic job sorting machine(AIKTC, 2021-05) Shaikh, Rizwan; Thonge, Zaid Azim (18DME55); Kazi, Salman Siraj (18DME34); Petkar, Muzammil Ashraf (18DME31); Tulve, Mustafa M. Hanif (16ME91)Sorting is very important in any type of industry such as manufacturing industry to improve the efficiency of manufacturing processes . Generally the manufacturing industries keep on manufacturing similar models of products with little variation in their height, color, weight and shape. Hence, sorting plays an important role there. In older days, it was possible to utilize manual labour for sorting the objects. But in the world of technology today where there are speed running industries, the production rate has increased tremendously. In such cases industries can’t bear human errors for sorting these products that too associated with high labour costs and time taking procedures. This gives rise to the necessity to reduce manual effort and also human error by replacing the conventional methods of sorting in areas involving hectic sorting with cut-cost user friendly automated systems. The goal with “Automatic Job Sorting Machine ” is to create a smart prototype model in which instead of using manual inspection and sorting here we are introducing an automatic system . In this type of conveyor system , sensors (i.e Ultrasonic and Ir) are used to measure the dimensions of parts placed over it and a linear solenoid is placed next to the sensor which will separate the component based on its dimensions. By using this system, we completely eliminate manual work and reduce inspection time , effort in material handling and also increase production rate.Item Design and analysis of hybrid vertical axis wind turbine with upstream wind deflectors(AIKTC, 2022-05) Shaikh, Rizwan; Tamhane, Tushar (18ME116); Sagale, Kunal (18ME77); Sayyed, Asgar (18ME84); Patil, Harshal (18ME60)India is currently facing energy crisis with its major dependency on coal, crude oil imports to meet sharply growing energy needs of producing energy by renewable sources .the compound annual growth rate for wind generation has been 11.39 percent between 2010 and 2022 .In recent years demand of energy has seen a rise in development of alternative energy sources such as wind power, solar power and water power. Wind being one of the most abundant and easily available sources is an excellent alternative to conventional energy sources. However the use of wind energy is increasing day by day wind turbines are gaining popularity in the fields of electricity generation. Vertical axis of wind turbine represent a very promising future for wind power generation. The stress induced due to turbulence on the surface of hybrid vertical axis wind turbine is low as compared to normal vertical axis wind turbine. Portability, and development cost is low this is an important factor to adopt vertical axis wind turbine, can be used for residential place as well as for personal use. Thus hybrid vertical axis wind turbine represent a unique technique of power generation. Hybridization involves integrating two or more turbines to increase in efficiency thus the concept of Hybrid vertical axis wind arose which is the base of the whole project. Hybrid vertical axis wind turbine are environment friendly structure that convert the kinetic energy in to electrical power .by reducing 80% of cost it is considered as the cheapest type of renewable energy source due to increase in demand in urban as well as in residential areas.Item Design and analysis of pressure vessel(AIKTC, 2018-05) Shaikh, Rizwan; Sayyed, Kazim (14ME43); Khan, Mohd.

The channel has a cross-section of 100x250 mm2. The experiment covered the following range Re=13,500-42000, Clearance ratio=0, Inter –fin spacing Sy/D=1.208, 1.524. Co-relation equations were developed for the heat transfer, Friction factor, Effectiveness. The experimental result showed that the use of cylindrical fin gives the max heat transfer enhancement. Effectiveness varies from 1.1-1.5 depending upon the inter-fin spacing. The friction factor also decreases. Thus the maximum effectiveness is obtained at minimum velocity and more inter-fin spacing. The average Nusselt number calculated on the basis of projected area increased with decreasing inter-fin spacing ratio. The friction factor increased with decreasing inter-fin distance ratio. Enhancement efficiencies increased with decreasing Reynolds number. Therefore, relatively lower Reynolds number led to an improvement in the heat transfer performance.Item Improvisation and fabrication of rake test rig used for air brake leakage testing in railways(AIKTC, 2019-05) Shaikh, Rizwan; Shaikh, Mustaq Ibrahim [15ME104]; Raza, Mohd.
