A highly underexpanded jet outflow into the background in transition and scattering regimes is studied computationally. The direct simulation Monte Carlo method and Navier–Stokes equations are used. The main parameters’ impact on the jet flow is

An expansion of the Cu vapor from the source into vacuum accompanied by cluster formation has been studied. Numerical modeling was implemented within the direct simulation Monte Carlo method. Considered range of parameters corresponds to transient an

The general approach for solving kinetic equations for gas mixtures with internal degrees of freedom and for deriving corresponding equations for reaction and relaxation rates (Kolesnichenko and Gorbachev, 2010, 2012, Gorbachev 2016) is ex-ploited fo

Two approaches to evaluate the mixture composition with a small reactive admixture for the gas flowing through a cylindrical channel are compared. Both are based on solving the Navier-Stokes equations. In the first one, the Navier-Stokes equations ar

A DSMC method making it possible to describe the formation and increase of clusters on the basis of the nucleation theory taking into account the corrections to the classical theory for description of small-size clusters has been developed. The probl

For the purpose of simulation of diamond-growth processes, the comparison of reacting gas flows modelled in a heated cylindrical channel has been performed by two different approaches: DSMC method and solution of Navier-Stokes equations. The impact o

Strong deviation of chemical reaction rates from their equilibrium values in vibrationally non-equilibrium gas is shown. Performed analysis is based on a new approach for solving the generalized Boltzmann equation. It allows to overstep the limits of
