Semi-empirical model of the combustion wave in a gas suspension of magnesium particles

A physicomathematical model within the framework of the approach of mechanics of reacting heterogeneous media is proposed to describe the combustion wave in a mixture of a gas and fine magnesium particles. The model is verified on the basis of dependences of the limiting temperature of ignition and combustion wave velocity on the radius and volume concentration of particles. It is guaranteed that the model is valid in the range of particle radii from 7.5 to 35 $\mu$m and in the range of volume concentrations of particles (1.2–2.4) $\cdot$ 10$^{-4}$.
