Turbine Burners: Turbulent Combustion of Liquid Fuels

Abstract

The proposed theoretical/computational and experimental study addresses 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 results from the demonstrated potential for immense improvements in the performance of gas turbine engines via combustion in the turbine passages. This program will address various fundamental issues concerning liquid-fuel combustion in an axially and centrifugally accelerating flow. The major combustion challenge involves ignition and flame-holding of the spray flame in the high-acceleration flow and associated optimization of the injection of the liquid fuel and some secondary air into a protected recirculation zone provided by a cavity.
