Combustion Efficiency of Boron-Containing Particles of the Condensed Phase in Channels with Distributed Injection of Air

A mathematical model and results of calculations of combustion of boron-containing particles of the condensed phase in channels with distributed injection of air are presented. Combustion in channels with discrete and continuously distributed injection of air is considered. Basic effects of the air-to-fuel ratio, place of air injection, and air temperature at the channel inlet on the combustion efficiency are analyzed. Conditions that ensure enhancement of the efficiency of particle combustion in the channel owing to distributed injection of air are determined. The data obtained in the present study can be used at the stage of design and experimental investigations of promising propulsion systems with the use of boron-containing high-energy-density materials as a fuel.
