Academic Projects

ROLLOVER CRASH SIMULATION BY PASSENGER VEHICLE OR PU TRUCK BY FE MODEL: 04/2015

Performed quasi-static roof crash simulation based on FMVSS-216 procedure.

Positioned a HIII 50% dummy in the front passenger seat and simulations for various injury criteria is analyzed.

Performed dynamic drop simulations based on Malibu II procedure.

Roof deformations for various design parameters using Taguchi method is calculated.

Results to find the most sensitive design parameter in terms of roof strength and deformation is calculated and

analyzed.

Software Used-Hyper mesh and Ls dyna

F ATIGUE ANALYSI S OF A FLIPCHIP PACKAGE USING HYPERMESH & ABAQUS: 0 4/2015

Created a 3D model of solder bumped silicon flip chip package in Hyper Mesh with thermal loading conditions

Meshed the model in hyper mesh with different element order.

Conducted Fatigue analysis using ABAQUS CAE to find loading conditions causing failure of the product.

THERMAL MODELING OF ELECTRIC VEHICLE BATTERY PACKS: 07/2014

Conducted CFD simulations to find out the transient temperatures in 15-cell lithium iron phosphate battery pack using

ANSYS FLUENT for an unmanned ground vehicle under worst case power draw conditions.

These simulations were conducted to determine the risk of thermal runaway under maximum power usage.

Designed the battery pack, defined UDF for the CFD simulation which adequately modelled temperature distribution in

the pack over time. The analysis revealed that the batteries reached unacceptable temperature of peak power usage.

CFD SIMULATION OF CATALYTIC CONVERTER IN AN IC ENGINE USING ANSYS (FLUENT): 11/2014

Conducted a Fuel flow, Fluid mechanics & Heat transfer analysis of a liquid ammonia fuel inside a catalytic converter

of an IC engine with the peak power output of 200kw.

Modeled the 3D Catalytic converter in UGNX 8 with different shapes of the inlet pipe connected to the Inlet of

the catalytic converter. Used Ansys Fluent to model the fuel flow and the catalyst reaction inside catalytic

converter.

Applied Fluid Mechanics and Thermodynamics principles to evaluate 1D result and these results were

compared with 3D CFD results which were summarized to be same with some general calculation error.

OMNI DIRECTIONAL MOVING TROLLY FOR MATERIAL HANDLING: 07/2012

Designed and fabricated a four wheel chassis for material handling.

Developed a gear mechanism to have rotating base for all the four wheels powered by a single motor.

Designed & fabricated the control button for central drive gear, steering all the four wheels to the required position.

Experience

Laboratory Assistant-CFD Simulation 08/2014 to Current

Wayne State University Detroit, MI, USA

Studied the applicability of new concepts using fundamental research with high speed imaging, spectral analysis and

CFD technique to propose new concepts and new diesel technologies contributing for engine design and product

development.

Implemented CFD technique which is used for fluid and thermal product design to evaluate the newer types of injection

spray and combustion inside chamber of a RCM very well using commercial software ANSYS FLUENT & CONVERGE.

Simulation of air flow, spray, combustion inside the combustion chamber of a rapid compression machine was carried out

using CFD software’s ANSYS FLUENT & CONVERGE and model development was done in Uni Graphics.

LILT (late injection low temperature) combustion system tested on rapid compression machine using high speed

photography & spectral analysis, results compared to CFD simulation result & reported the same.

Sub System Engineer-Thermal Management 08/2014 to 12/2014

Formula Hybrid SAE Wayne state motorsports Detroit, MI, USA

Part of team responsible for design and analysis of an electric vehicle battery pack for our formula hybrid car.

Completed benchmarking the design of clamping wedges and end plates that holds the battery pack.

Proposed DFMEA spread sheet on tools holding the battery pack inside the car to see whether wedges and plates

can sustain the rapid loading and temperature from the results obtained from FEA Analysis.

Presented a paper regarding thermal management of battery pack to find the maximum peak temperature under worst

case power draws using CFD technique.

Graduate Engineer Trainee 07/2012 to 10/2013

Mallikarjuna Motors PVT Ltd Davangere, INDIA

Maintained timely and accurate oral and written technical reports regarding assigned engineering activities regarding service of

the delivered new vehicles.
