OBJECTIVE: To obtain a full time position and to utilize my technical

skills & knowledge in thermal related fields specifically

engines testing, validation, combustion and

emissions/Aftertreatment.

EDUCATION: Currently pursuing Masters in Mechanical Engineering at

Michigan Technological University (MTU), USA,2012.

. GPA: 3.53/4

Bachelor of Engineering- Mechanical Engineering, Visvesvaraya

Technological University, Belgaum, Karnataka, India averaged

80%.

. Class: First Class with Distinction

PREVIOUS JOB

EXPERIENCE: Worked in CUMMINS INC from May 2012 to Nov 2012 as

Combustion, Performance and Emissions Engineer.

. Ran an Engine Test Cell working on Calibrations and Testings.

. Worked on a Deterioration Factor test of an engine.

o Formulated the entire test process and required

analysis.

o Analyzed data and other critical issues regarding the

engine performance.

o Detailed understanding and working with the

Aftertreatement system in an engine and its impact on

the performance of the engine.

INTERN

EXPERIENCE: Design Assistant, SMARTCAD ENGINEERS, Bangalore, India,

June 2008 to July 2009.

. Worked in 2D and 3D environment using AutoCad and CATIA.

. Designed and assembled various machine components.

. Generated 2D drawings.

PROJECT

EXPERIENCE:

> 'Optimizing Machinability Using Statistics', Bangalore, India,

from Jan 2010 to April 2010.

. Member of 4 person team

. Optimized various cutting parameters

. Found the order in which the materials are ranked based on

their machinability parameters.

. Ferrous metals are generally tough to machine.

. Cast iron has got the best machinability, followed by the

stainless steel and then mild steel.

> Engine simulations in GT Power of a 4- cylinder SI Engine,

Michigan, USA from Jan 2011 to April 2011.

. Acquiring Engine performance parameters like in-cylinder

pressure, generating P-V diagrams (to find compression and

expansion works) and analyzed results in GT Post.

. Explored effects of Fuel/ Air ratios on brake powers, analyzed

BSFC's and NOx emissions for different fuels.

. Analyzed the impact on fuel economy and determined the

expected improvement in fuel economy (miles/gallon) upon

activation and deactivation of cylinders.

. Studied the effect of Exhaust gas recirculation (EGR) as an

effective tool to reduce NOx emissions.

. Found that higher cylinder pressures will not essentially

result in high torque output. It also depends upon the net

work/power (difference of expansion and compression

processes).

. Different fuels have different energy content and this has an

impact on the brake power and BSFC's. But NOx emissions were

dependent on the Equivalence ratios. NOx emissions decreased

as Equivalence ratios increased.

. Calculated and observed that the fuel economy of a 4-cylinder

(half) activation was greater that 8-cylinder (full)

activation. The reason for this was higher throttle angle in a

4-cylinder case reducing the pumping work which increased the

power out and thus the fuel economy.

> 'Product Composition and Adiabatic Flame Temperature Estimation

for Hydrocarbons', Michigan, USA from Jan 2011 to Feb 2011

. Found and calculated the products, its composition and

Adiabatic Flame Temperatures for Stoichiometric, Lean and Rich

mixture cases in MATLAB.

. Inputted the hydrocarbon into CHEMKIN and found the products

for Stoichiometric, Lean and Rich mixture cases.

. Compared the CHEMKIN and MATLAB solutions for the above.

. The Adiabatic Flame Temperatures in MATLAB was greater than

CHEMKIN. This was because CHEMKIN considered more dissociation

reactions. As more and more dissociation occurs, the Adiabatic

Flame temperature continues to fall.

. The composition of products was almost same in CHEMKIN and

MATLAB with a minor difference.

> 'NO and NO2 formation in the Combustion of H2 with air',

Michigan, USA from March 2011 to April 2011

. Aimed to determine the product mixture composition and

temperature of NO and NO2 in an adiabatic Perfectly Stirred

Reactor (PSR) - actual and equilibrium reactions.

. CHEMKIN simulations were done to predict molar fractions of

products as a function of Equivalence ratio .

. Time rate of change and mole fractions of NO concentrations

were determined using Zeldovich Chain Reactions.

. NO formation model in MATLAB with varying ? and comparing it

with the CHEMKIN data.

. Maximum NO production was seen at ? = 1.05 & ?= 0.8 for the

actual reaction and equilibrium cases respectively and NO2 at

? = 0.85 and ?= 0.6 for the actual reaction and equilibrium

cases.

. Maximum reaction temperature of 2146.996K was seen at ?= 1.1

for a PSR and 2394.289K at ?= 1.05 for equilibrium case.

. The difference between the PSR (actual) and Equilibrium case

was because of the small residence time in PSR (1 millisecond)

which was not enough for all H2 to get converted to H2O.
