ОБ УПРАВЛЕНИИ ИНТЕНСИВНОСТЬЮ КОНВЕКЦИИ ХИМИЧЕСКИ РЕАГИРУЮЩЕГО ГАЗА
Abstract
A linear analysis of the stability of Rayleigh-Benard static regime convection is performed in a chemically reacting equilibrium hydrogen-oxygen gas mixture with added chemically inert microparticles of aluminum oxide. It is shown in the Boussinesq approach that a suitable choice of temperature can intensify convection and adding chemically inert microparticles can suppress convective motion. It is established that the isobaric convection regime is realized when the height of the region is less than the critical value, and when the height of the region exceeds this critical value, the convection regime is superadiabatic. During convection in the superadiabatic regime, its adiabatic suppression is observed. Within the framework of the isobaric convection regime, the limits of applicability of the Boussinesq approach are determined.
