Stability of combustion of powder in a phenomenological model with nonadiabatic flame

Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

A stability criterion for combustion of powder is obtained, taking into account the effect of the processes in the gas phase. It is shown that consideration of the effects of a nonadiabatic flame leads to the stability reserve of combustion being reduced and the natural frequency of vibrations being lowered. The effects thus found are physically explained by the radiation of a part of energy from the combustion zone with thermal and acoustic waves.
