For the master's project, the modelled device is a regenerative solid state tensile elastocaloric cooling setup which is an alternative to vapor compression systems. The device uses Nickel-Titanium (NiTi) shape memory alloy (SMA) as the solid state coolant. Further, an experimental setup with servo motors, belt drive and pneumatic cylinders was also designed to realize the model. Three unique design concepts were proposed for the cooling device along with the calculations for each concept.

IIT Bombay Racing team is a cross functional team of 70+ students that designs and builds an electric race car for Formula Student UK, a prestigious international students design competition organised by Institute of Mechanical Engineers (IMechE).

As Chief Mechanical Officer, I led the design of suspension, steering, brakes, wheels, electronic differential and vehicle dynamics modelling. I also held the responsibilities of on-track testing, design presentations and vehicle readiness for the dynamic events at Silverstone, UK.

This paper describes the experimental study performed on solidification of transparent (hyper-eutectic ammonium-chloride in water) salt solution in a bottom-cooled condition. Due to the rejection of low-density water-enriched component, convective flow channels in the form of plumes are generated. Due to the action of this flow, dendritic particles were found to break off. A microscopic camera was used to record their movements. The velocity of these particles, as they flow with the plume was measured and correlated with the plume velocity. The particle tracking and velocity measurements were done using a MATLAB code. The findings were presented in the National Conference on Fluid Mechanics and Fluid Power (FMFP) in December, 2017.

The aim of this device is to replace manual cutting of vegetables using a mechanical device without any control system involved. The device is targeted towards medium to high consumption (few hundred to thousand vegetables per day) applications like restaurants, mess kitchens, event catering etc. The device consists of two major components - i.) A conveyor belt to carry and move the vegetables and ii.) A slider crank mechanism, which holds the cutter, to cut the vegetables.
