Formation and Diagnostics of Sprays in Combustion

Abstract

Fuel-air mixture preparation is a key factor determining combustion performance and emissions in a variety of practical applications, such as internal combustion engines, gas-turbine engines, rocket propulsion devices, and power generation systems. The problem of characterizing the two-phase combustion process is quite difficult, in part because of the complex optical interactions involved, and in part due to the optically dense nature of many sprays. Many techniques are currently employed for the characterization of spray combustion processes, with the selection of appropriate measurement technology dependent upon the nature of the spray for each combustion application.
