"Towards High-Efficiency Low-Emission Combustion Design:  Multimodal Combustion and Soot Emissions"

Tuesday, February 21 @ 1:30 p.m.
Montgomery Knight Room 317

Abstract

Transportation, power generation, and electricity generation depend heavily on the combustion of fossil and synthetic fuels.  The next generation of combustion systems will need to be more efficient with lower emissions than the current.  In this talk, I will discuss the coupling effects of two crucial components of combustion, chemical kinetics and fluid dynamics, on flame dynamics and soot emissions, and the physical insights for future combustion design.  Specifically, I will discuss 1) multimodal combustion that consists of both deflagration and autoignition under elevated temperatures and pressures and 2) soot evolution in turbulent reacting flows that represent the recirculating patterns in gas turbines.  I will conclude with future research directions that combine combustion and material sciences to develop new technologies for energy sustainability.
