Aided Combustion of Liquid and Gaseous Fuels Injected Transversely into a Supersonic Air-Stream.
Abstract
An investigation has been made of the sustained combustion of transversely injected fuel jets in an enclosed Mach 2 air-stream. Hydrogen, methane and kerosene were employed as fuels. High-enthalpy test-air was supplied from a pebble-bed regenerative heat exchanger through a Mach 2 two-dimensional nozzle. The stagnation temperature of the test-air could be varied within wide limits, but for the studies reported here, had a maximum value of about 1800K. The favorable flame stabilization effect of the obstruction caused by a fuel jet injected transversely into the supersonic stream has been demonstrated. Two non-dimensional quantities have been proposed and have been shown to effectively describe the fluid dynamic effects associated with the flame stabilisation process. The two proposed non-dimensional quantities have been used in studying the effect of the interaction between the pilot and the main fuel injection configurations. (Modified author abstract)
