MODEL OF EVOLUTIONOF FINITE-AMPLITUDE PERTUBATIONS IN A TWO-PHASE REACTIVE SYSTEM

ABSTRAKT
The dynamics of weak finite-amplitude perturbations in a homogeneous gas suspension (reactive gas mixture and chemically inert solid particles) is considered. A weakly nonlinear model takes into account the chemical kinetics−gasdynamics interaction and dissipative properties. The influence of interphase heat and momentum exchange on the stability of the homogeneous state of a system is analyzed. For the model kinetics of the reaction, numerical solutions of the evolution equation are obtained in the form of steady self-oscillations. A sharp increase in the characteristic period of self-oscillations and instability suppression in gas suspension with small-size particles are described.
