Summary
Experience of 5 years in numerical modelling combustion and exhaust aftertreatment components.
Experience of 2 years in experimental study of incipient soot formation and growth in a Tube Reactor (Ongoing).
Strong background in fluid dynamics, thermal science and combustion.
Highly competent in LabVIEW, ANSYS, C/C++, FORTRAN, CHEMKIN and MATLAB.
EXPECTED GRADUATION: April 2015
WORK EXPERIENCE
July 2011 – July 2013
Caterpillar (CAT) India, Engine Research Team
Associate Engineer
Model Development and Validation (Aftertreatment)
Developed a detailed 2D numerical model in Matlab and C++ to perform simulation of new technology Vanadia - SCR catalyst
with detailed chemistry and transport equation in an implicit solver .
The model was designed to simulate all flow through aftertreatment components like Diesel Oxidation Catalyst (DOC),
Selective Catalytic Reduction (SCR) and Ammonia Oxidation Catalyst (AMOx).
Developed capabilities in the model to simulate thermal, hydrothermal, phosphorous and sulfur ageing of catalysts. This helped
in saving 1000-5000 hours of catalyst testing for ageing.
Calibrated and validated the model to engine test cell data running NRTC (Non Road Transient Cycle) and other CAT machine
cycles.
Other Projects
Successfully completed the High NOx Conversion Efficiency Project where model of SCRF (a combination of DPF and SCR)
was integrated in Dynasty (Caterpillar in-house tool) and was validated with NRTC cycle. This project targeted an engine
system cost reduction of 20% relative to conventional system
Integrated a physics-based model of SCR (Matlab Simulink) as HIL (hardware-in-loop) into ECM of Caterpillar Large Engines
as a part of Emission norms of Tier 4 final technology selection.
Awarded Certificate of Appreciation by Gwenne Henricks, Vice President, PD>, Caterpillar Inc. for outstanding contribution
to CAT EDC India during 2012-2013.

Graduate Research Assistant
In situ sampling of nano-sized soot particles
Particle size distribution functions (PSDFs) and mean particle sizes of soot particles produced from a fuel -rich, premixed flat
flame (McKenna burner) were obtained by probe sampling and online analysis using a Nano Scanning Mobility Particle Sizer
(n-SMPS).
Using this technique bimodal soot particles size distributions were obtained for a size range of 3nm-100nm.
The emphasis of the work was the development of an in situ sampling technique to follow the evolution of nanoparticles formed
in flames.
Experimental study to understand the soot formation and growth in a Micro -flow Tube Reactor.
The new sampling technique is used to obtain soot PSDFs for fuel (C2-C4) pyrolysis and oxidation using n-SMPS.
The distribution of sizes of soot particles for different residence time, temperature (up to 1250K) and fuel concentration ar e
obtained.
The data obtained is used to validate soot growth model based on soot nucleation through Pyrene formation and sectional
growth.
Zero-D Fortran model of soot growth
Developed a Zero-D FORTRAN numerical model to simulate soot particles inception and subsequent coagulation and surface
growth (HACA mechanism). CHEMKIN was used to model gas phase reactions and sectional modeling was used to model
soot growth.
Jindal Steel and Power Ltd, India July 2010-June 2011
Graduate Engineer Trainee
On-job training in Turbine and Generator Maintenance Department in JPL Tamnar, a 1000 (4x250) MW power plant.
Developed detailed guidelines for trouble-shooting and understanding the Turbine Governing System as part of departmental
assignment.
University of Minho, Guimaraes, Portugal May2009 - July 2009
Summer Internship
A 1-D numerical model of a 4-stroke single cylinder Diesel engine was developed in Matlab Simulink. Different temperature and
pressure curves were obtained by varying the dimensions of cylinder, equivalence ratio, valve opening or closing time, crank angle
of fuel injection etc. A frontend for the model was also developed.
Suzuki Powertrain India Ltd May 2008 - June 2008
Summer Internship
Familiarization with the engine assembly line, the transmission assembly line and machining process of different engine compo nents
in the inline 4 cylinder diesel engine manufacturing plant. Studied the qualitative aspects of various components of the diesel engine.
IIT Guwahati Jan 2010 - April 2010
Bachelor Thesis Project
Noise and Vibration control of machineries used in silk processes. In this project visits were undertaken to a cottage silk industry
in Assam, India to study noise and vibration related problems of the machines. A number of sources of noise were identified a nd
remedial suggestions were implemented, thereby reducing noise and vibrations in the machines.
