Abstract

Particle Image Velocimetry (PIV) and Colour-Schlieren measurements have been used in order to investigate the combustion process of solid fuel slabs with boron particle addition in a step combustor under ramjet relevant conditions concerning the air inlet temperature. The high time resolution of both measurement techniques (-13 µs for Schlieren and 10 ns for PIV) show a quasi frozen state of the flow. With both techniques large scale vortical structures were observed in the outer zone above the diffusion flame in the developing boundary layer behind the recirculation zone.
