Investigation of a multiphase diffusion flame (Al+H2/Air) with a flat flame burner

Abstract

The addition of metal particles, like Aluminum or Boron, to typically used hydrocarbon binder is an interesting topic for advanced propulsion system like air breathing ramjet engines, ducted rockets and so on; in fact this is due to higher gravimetric and volumetric combustion heat capacity of metal additive in comparision with conventional solid fluids. T main purpose of the present research is to investigate the general structure and topoloy of the multiphase diffusion flame of Aluminum particles embedded in a Hydrogen jet within an hot air environment, concerning the ramjet relevant conditions match air inlet temperature.
