Abstract

In order to get a better insight in solid fuel ramjet combustion processes the combustion behavior of solid fuel slabs with and without boron particle addition had been investigated in a planar step combustor under ramjet relevant conditions concerning the air inlet temperature. Various intrusive and non-intrusive diagnostic techniques had been used to analyze the highly turbulent multiphase combustion process. Large scale vortical structures can be seen in the outer zone above the diffusion flame in the developing boundary layer behind the recirculation zone with Colour Schlieren as well as with PIV. Distributions of the gas phase temperature, velocities of reacting particles as well as concentrations of stable reaction products have been determined and are presented here, too.
