· PACE (Partners for Advancement of Collaborative Engineering Education) is a global initiative by General Motors, Oracle, Hewlett Packard, and SIEMENS-consisting of 65 universities from 10 countries. Worked on development of PUMA(Personal Urban Mobility Access)- a portable electric vehicle for senior citizens- in a collaborative project with universities from Brazil, Germany, India, and USA
· Responsibilities include target market identification and customer survey, conducting design and analysis using NX, ANSYS, and Hypermesh. Training new recruits and communication with international teammates.
· 3rd place globally among 65 universities in 10 countries at the “Collaborative innovative Challenge” competition for “Use of hybrid-nanofluids in automobile radiators” at PACE Annual Global Forum, Toluca, Mexico, 2017.
· 2nd Prize at the “Technical Paper Presentation” competition for “Improvement of radiator performance by hybrid nanofluids” at PACE Annual Global Forum, Toluca, Mexico, 2017.
· Development of PUMA electric vehicle as part of Team 3- in collaboration with University of Sao Paolo And Institutio De Maua (Brazil), University of RheinMann (Germany), MTU, (USA) and NID Ahmadabad (India) was awarded in Market Survey (1st-2017&3rd-2018),Design(2nd-2017),Product Engineering(2nd-2018),Manufacturing(2nd-2017&1st-2018) and SIEMENS PLM Excellence award(2018) at PACE Annual Global Forums, Toluca, Mexico(2017) and Michigan, USA(2018).
· Recipient of MHRD scholarship for academic merit by Government of India during all four years of engineering.
· Preparation and investigation of hydrophobic and hydrophobic surfaces using abrasion and chemical etching, is proposed to enhance heat transfer. Initial experimental results indicate significant increase in heat transfer decrease in pressure drop by the use of these surfaces.
· Use of graphene-based nanofluids, prepared with a specific process and concentration (patent pending) resulted in over 200% enhancement in thermal efficiency of automobile radiators as compared to commonly used water-ethylene glycol coolants. CFD analysis of the effect of nanoparticles in a coolant to enhance cooling was also investigated using ANSYS Fluent for a typical radiator element.
· A simple method was developed to determine the junction temperatures of different dies in a 5 die, microelectronic package using the linear superposition principle and validated with analysis using the Thermal module in ANSYS workbench suite. The method eliminates the necessity of time-consuming simulations to obtain approximate temperature values with errors less than 3%.
· A numerical analysis of heat generation in a single Cylindrical Li-ion cell based on chemistry was performed and viability of different thermal management strategies [air cooling, liquid cooling] was determined using ANSYS Fluent package. Two thermal management designs were developed involving liquid cooling with cold plates and microchannels with ANSYS Fluent software to maintain a cell temperature less than 40 0C.
