metadata.name: dc.description.abstract
metadata.value: Various relaxation stages of gas flows with physical and chemical processes are considered
  in zero- and first-order approximations of the modified Chapman Enskog method in terms
  of intensive parameters which are conjugated to governing extensive ones for this relaxation
  stage. To simplify the transport processes investigation, the model kinetic equations are
  used. In these equations the BGK-type operator substitutes a group of collision operators
  which describe the forming of the quasi-stationary distribution functions on the relaxation
  stage under review. Proposed model equations can be used for the study of any equilibrium
  and non-equilibrium regimes of the flows when strong deviations from the equilibrium
  distributions over chemical species and part of internal energy are observed along with weak deviations from equilibrium of translational energy and remaining part of the internal
  energy. The expressions for transport fluxes are given in terms of intensive parameters.
  The formula for sound velocity (as the velocity of propagation of small perturbations) with
  coefficient æ which is not constant in considered conditions is given.
