Organization of Effective Combustion of Kerosene in a Channel at High Flow Velocities

Abstract

A new method of initiation and effective burning of kerosene at supersonic velocities of the flow in a constant-section channel is considered as applied to combustion chambers of variable geometry. The regime of intense combustion occurs due to an external action of a package of gas-dynamic pulses with the energy varying in time. It is experimentally observed that this regime is retained if the action is terminated after the combustion process is organized in the expanding part of the combustor. It is demonstrated that the proposed method can be applied at flow temperatures and high velocities at which kerosene combustion is impossible without special tools for flame stabilization.
