Abstract: This paper presents a mathematical model and the results of calculation of the velocity of propagation of the flame front in a fuel gas with suspended inert particles taking into account the thermal expansion of the gas and the dynamic relaxation of particles. Dependences of the steady-state flame velocity on the particle size and mass concentration are obtained.

Keywords: gas suspension, laminar flame, thermal expansion, inert particles.
