Convective Combustion of a Ti + 0.5C Granulated Mixture. Domain of Existence and Fundamental Phenomena

Abstract

Combustion of a Ti + 0.5C granulated mixture with a varying rate of the coflow of nitrogen is under consideration. Experimental data are used to determine the gas flow parameters responsible for the transition from conductive to convective propagation of the combustion wave, which is characterized by a stronger dependence of the burning rate on the value of the gas flow. A simple model for calculating the burning rate in convective combustion, and a method for determining the boundary between combustion regimes is developed. In accordance with this model, the burning rate not only depends on the combustion temperature of the mixture, but also on the ignition temperature of the mixture components in the flow of active gas
