Abstract
A physicomathematical model of the Rayleigh-Benard convection in a chemically equilibrium gas containing chemically inert microparticles (Al2O3) is proposed. A linear analysis of convection in the Boussinesq approximation is performed. It is shown that addition of chemically inert microparticles increases the critical value of the Rayleigh number and stability of the convective process. The possibility of using chemically inert microparticles for control and monitoring of convection in a chemically reacting gas is demonstrated by an example of a chemically equilibrium gas.
