Liquid Fuel Combustion: Liquid fuels are used in many energy generating
devices, such as diesel engines, liquid propellant rocket engines and
gas turbines. The efficiency of these devices is intimately dependent
on the mechanism of the combustion of the droplets in the fuel spray
used in them. We are involved in the combustion characterization of
various fuels. This is done by developing computational models for the
combustion processes involving fuel sprays and verifying our
computations with experiments.
