Paper Abstract

Optical diagnostics play a key role in the development of a unique, high volumetric heat release rate incinerator design at UCLA. In the device, a derivative of an aerospace dump combustor, a pre-mixed flame is stabilized within a rectangular duct by a sudden expansion in cross section at the dump plane. Wastes injected into hot, oxidative recirculation regions downstream of the dump plane experience much larger residence times than those of the bulk flow. Particle Image Velocimetry is used to study the velocity field in the combustion cavity. The results confirm the existence of the recirculation regions and illustrate the effect of waste injection on them. Planar Laser-Induced Fluorescence of the OH radical illustrates the propagation of a vortical reaction zone (flame) into the combustion cavity and its interaction with the recirculation zones.
