Annotation:  In this work, the process of gas suspension flowing into vacuum numerically modeled. The mathematical model took into account the viscosity, compressibility and thermal conductivity of the carrier medium, the intercomponent force interaction, which included the Stokes force, the dynamic Archimedes force, the strength of the attached masses, and the mathematical model took into account the intercomponent heat transfer. The numerical solution carried out using an explicit finite-difference method, followed by the application of a nonlinear correction scheme for the numerical solution. The aim of the work was to identify the effect of the volumetric content of the dispersed phase, with the same dispersion and density of the material of the solid component of the mixture, gas suspension on the rate of slip during expansion of an inhomogeneous medium into vacuum. Differences in the processes of the expiration of a homogeneous viscous gas and a heterogeneous mixture it also revealed
