The method is designed for gas flows in which the flow field can be divided on some relatively small and highly non equilibrium (kinetic) zones, and the main area where hydrodynamic approximation is valid. The above division is made from a priori analysis of a problem and then could be corrected after some trial computations. Inside the kinetic zones one solve the Boltzmann equation by regular finite‐difference method, and in the main area one apply the Navier‐Stokes equations. For matching the solutions at the interfaces of the regions the Chapman‐Enskog distribution function is used. As examples of application of the method two cases of interaction of rarefied gas flow with a periodic grid are computed.
