Doctor of Philosophy (Ph.D.) in Department of Energy Science and Engineering 2020-2024
Indian Institute of Technology, Delhi, India

• To analyze the impact of depth of discharge (DoD) and temperature on heat generated inside Li-ion cells by precisely simulating the equivalent internal resistance and entropy change utilizing experimental data. The response of a Li-ion battery is analyzed using a two-dimensional transient electrothermal model developed. • Experimental and Numerical analysis of passive cell level cooling strategy using different PCMs for cylindrical lithium cell in automotive applications and optimizing the passive BTMS to find the optimum parameters effecting the performance.

• The research objective was to compare single and dual-axis tracking surfaces with a fixed surface regarding the percentage increase in average total irradiation. • The average total irradiation was calculated using isotropic models with the help of Solcast data in a MATLAB program. The MATLAB program helped to analyze, compare, and determine the increase in irradiation falling on the tracking surface. • The study also focused on a comparative analysis of the three isotropic models for the average monthly irradiation at Jodhpur. • Single and dual-axis tracking surfaces enhanced monthly total irradiation by 12.17 and 21.2%, respectively, compared to a fixed surface. The study demonstrates that Badescu and Liu&Jordan are more accurate.

B
Bachelor of Technology (B.Tech) in Mechanical Engineering 2012-2016
YMCA University of Science and Technology Haryana, India

• The Project's main objective was to construct a robot equipped with Mecanum wheels that can move in any direction. • The Arduino UNO platform was utilized for the robot's programming. • This work strived to develop a simple, affordable Mecanum wheel design for less than 5000 Indian Rupees. • The Project helped develop an understanding of design and production processes.
