Minneapolis, Minnesota, United States
Currently, I am pursuing a Ph.D. in Mechanical Engineering at the UMN, focusing on spray cooling thermal management, nanoparticle modeling, and flow visualization. My research contributions include developing a patented spray cooling system that achieves exceptionally high heat flux removal from target surfaces and modeling the heat flux removal through 1D -heat transfer models. I also have experience in molecular simulations using LAMMPS to study crystal growth and have performed side projects in optical diagnostics, including Shadowgraphy and Holography measurements using machine learning. As a Thermal CFD Intern at Tesla, I modeled high-speed combustion flows during thermal runaway. I performed CFD simulations in STAR-CCM+ on CAD models from SpaceClaim, benchmarking the simulations against test data to inform design decisions and improve product safety during abuse scenarios. I also conducted Discrete Element Modeling (DEM) simulations to track ejecta during thermal runaway and accelerated the workflow by employing a data-driven predictive model. During my M.S. in Fluid Mechanics and Thermal Sciences at the Indian Institute of Technology, I designed a rotating experimental setup to study turbulent heat transfer caused by thermal buoyancy. The system included DAQ measurements from thermocouples, thermistors, and RTDs, as well as optical access for PIV. To complement this experimental work, I performed Direct Numerical Simulations using the in-house C++ code SARAS. I have 1.5 years of work experience in the aerospace industry at the Indian Space Research Organisation (ISRO), where I designed satellite payloads like antenna dishes to withstand extreme thermal and structural loads using HyperMesh (FEA) simulation on CAD models from NX. I tested these components through thermal cycling in a thermo-vacuum chamber, performed vapor coating to achieve a precise surface finish, and benchmarked them for vibration on shakers. I also have experience in characterizing the thermal conductivity of various composites: Kevlar, Carbon fiber reinforced with various honeycomb, using the laser flash appratus and table top experiment My academic contributions include first-author publications in Physical Review Fluids (PRF) and the Journal of Chemical Physics.
