Anomalous Effect of Turbulence on the Combustion Rate of a High-Energy Solid Material

Abstract

Study of the practice of using solid rocket fuels and explosives has determined the existence of an increase in the combustion rate due to turbulence. However, this rule is violated in the case of small-scale turbulence produced by the gasification zone of solid fuel. The incoming heat from the gas phase is partially consumed to maintain the chemical reaction of gasification and partially returns to the gas phase. If the return energy of turbulent motion is high, then the combustion rate decreases.
