OBJECTIVE

Looking for a full time position in a reputed company where I can put my technical knowledge

to use, contribute to the company's growth and also hone my professional skills.

EXPERIENCE

Research Assistant at University of Texas at Arlington, Arlington, Texas

July 2011 – May 2012

Effect of pre-shock turbulence on post-shock fluctuations in detonation waves: Dynamic

Mode Decomposition (DMD) was used for the analysis of transversely unstable

detonations. WENO scheme was used to get the flow field solutions and DMD was

applied on these solutions for the analysis. Analysis showed that fluctuations just behind

the shock are due to the thermo-acoustic instability and regions downstream of the shock

are affected by the convected turbulence. Single step chemistry was assumed for the

analysis.

Student Lab Assistant at University of Texas at Arlington, Arlington, Texas

August 2011 - May 2012

Intern at Bosch India Limited, Bangalore, Karnataka, India

February 2009 – May 2009

Implementation of Pull System: Movement of components within the manufacturing plant

was analyzed and changes were made so that the Kanban System and Pull System were

implemented in the plant.

PROJECTS

Detailed chemical Kinetics: A FORTRAN code using CHEMKIN-III was developed for

detailed chemical analysis taking 28 species and 10 reactions into consideration and it

was validated by solving equations of constant pressure combustion for hydrogen-air

reaction mixture. This detailed kinetics code will be incorporated into original WENO

scheme previously developed and DMD analysis will be carried out.

Comparing performance of ethanol and gasoline fuels: A 4-valve spark ignition engine is

considered for the engine simulations with ethanol and gasoline using KIVA. Thermal

efficiencies for both the cases were determined from the pressure vs. volume outputs.

Results showed that using ethanol as fuel is more efficient.

Using Mac-Cormack technique to find flow field solutions in a nozzle: The aim was to

illustrate the use of Mac-Cormack’s explicit finite difference technique to solve for quasi-

one dimensional flow through a convergent divergent nozzle. The code was written in

Matlab.
