Research Title:

Numerical simulation of ignition and flame propagation in lean premixed combustion and pollutants prediction


Research Description:

As emissions standards worldwide are becoming more and more stringent, the need for low emission combustor technology is being explored to meet emissions regulations and improve fuel economy. Numerical modeling and simulation of turbulent combustion provide better insight into the flow physics and thereby provide great assistance to the development of low emission engines. The objective of my research is to predict the turbulent flame characteristics and pollutants (NOx, CO, UHC, particulate matter and smoke) and validate with experimental data. Turbulent combustion involves complex physical and chemical processes. My research involves modeling of turbulent lean premixed flames using Large Eddy Simulation (LES) for turbulence and partially premixed model based on mixture fraction and progress variable for combustion.

About Me:

I received my undergraduate degree in mechanical engineering from College of Engineering, Sri Venkateswara University, India. My work in the area of combustion simulation using commercial CFD codes for engine design analysis and pollutants prediction in the industry inspired me to do further research to acquire more fundamental insight in the area of computational combustion to improve the existing models for better predictions. My present work at Purdue involves modeling and simulation of ignition and combustion of lean premixed fuel – air mixtures for low emission gas turbine engine applications.
