Evolution of weak perturbations in gas-solid suspension with chemical reaction

摘要：

Dynamics of weak finite-amplitude perturbations in two-phase homogeneous medium (gas + solid particles) with non-equilibrium chemical reaction in gas is studied theoretically.Non-linear model of plane perturbation evolution is substantiated.The model takes into account wave-kinetic interaction and dissipation effects,including inter-phase heat and momentum transfer.Conditions for uniform state of the system are analyzed.Nonlinear equation describing evolution of plane perturbation is derived under weak dispersion and dissipation effects.The obtained results demonstrate self-organization in the homogeneous system: steady-state periodic structure arises,its period,amplitude and velocity depends on the features of the medium.The dependencies of these parameters on dissipation and chemical kinetics are analyzed.
