Activities

The
Lasers, Flames, and Aerosols (LFA) research group studies problems that
include nearly any intersection of the three aspects in the LFA name.
Sprays and spray combustion, laser measurements of soot aerosol
formation and dynamics, laser ignition of methane hydrates,
spectroscopic evauation of flames under the influence of electric
fields and near surfaces, are just a few recent examples.

Research Approach
|
Simplified
systems are developed that mimic a specific behavior of interest from a
more complex
practical. Thedominant physical process in the realistic system are
extracted from the fundamental understanding obtained from advanced
diagnostics and analysis applies to the laboratory scale experiments.
Examples include counterflow and coflow burners for nonpremixed flame
study, small reciprocating engines, droplet stream flames, and high
pressure chamber. In many cases, numerical
simulations are developed in conjunction with the experiments to
provide insight into influencing factors. Although our motivation
is always an improved understanding of a practical systems, diagnostic
tool implementations needed to meet these goals are concurrently being
evaluated to prove flexibility and accuracy in non-ideal settings.
