Turbine Burners: Turbulent Combustion of Liquids Fuels

Abstract

This theoretical/computational and experimental study addressed the vital two-way coupling between combustion processes and fluid dynamic phenomena associated with schemes for burning liquid fuels in high-speed, accelerating, and turning transonic turbulent flows. A major motivation for this type of combustion configuration was the demonstrated potential for improvements in the performance of gas turbine engines via combustion in the turbine passages. This program addressed various fundamental issues concerning combustion in an axially and centrifugally accelerating flow. The major combustion challenge involved ignition and flame-holding of a flame in the high-acceleration flow and the associated optimization of the injection of the fuel and some secondary air into a protected recirculation zone provided by a cavity. The objectives were to advance our understanding of liquid-fuel combustion in accelerating flows and thereby to contribute to the development of turbine-burner technology.
