Coaxial Dump Combustor Investigations

An experimental investigation was conducted involving coaxial dump combustors with two different types of flameholders annular and Y installed at the dump station in an attempt to correlate combustor performance with previous non-reacting flowfield results. Flameholder blockage, combustor length, exit area ratio, inlet temperature, and chamber pressure were varied for both all injection and premixed fuel conditions. Lean blowout limits, combustion efficiency, combustor total pressure drop, and wall static pressure distributions were obtained from these runs using JP-4 fuel. In addition, a limited amount of surface heating patterns and combustion oscillation data were obtained.
