TYPES OF STANDING WAVES GENERATED BY GAS COMBUSTION IN INERT POROUS-MEDIA

Stationary spherical waves of gas combustion in porous media are studi ed both theoretically and experimentally. It is shown that combustion waves in convergent and divergent gas flows differ in their stability: they are stable in convergent flows and unstable in divergent. The pr oposed simplified mathematical model of spherical standing waves relat es the standing wave coordinate to the gas flow rate, mixture composit ion, and parameters of the porous medium and gas and truthfully reprod uces the experimental results.
