Abstract: The review of some works fulfilled in the lab 20 of ITAM SD RAS in the domain of reactive/nonreactive heterogeneous media mechanics is presented. First part of the paper is devoted to the heterogeneous detonation problems (mixtures of aluminum or coal particles and oxygen) the 1D stationary (types of detonation flows) and nonstationary flows (initiation and stability problems), 2D nonstationary flows (some problems of initiations). The second part of the paper is devoted to acoustical convective drying of capillary-porous materials. Some mathematical model to describe this phenomenon is presented. Some experimental investigation to describe the phenomenon mechanisms is fulfilled for some materials (corn, wood).
