Combustion of Inhomogeneous Titanium + Carbon Black Powder Mixture

Abstract

The stability of combustion of titanium + carbon black powder mixture to a local excess of the component was experimentally studied. The influence of the spreading of titanium melt or liquid reaction product on the stability of the combustion transition through transverse carbon powder barrier was considered. The direction of melt movement with respect to the front propagation direction was determined. It was shown that the stability of the combustion transition through the barrier is determined by thermal interaction between the combustion wave and the barrier and is not directly related to the convective heat transfer by the melt.
