The flow models are considered in the first (Navier–Stokes) approximation. The effect of the volume viscosity coefficient on the solutions obtained is investigated with reference to the problem of the plane shock wave profile. It is shown that taking the volume viscosity coefficient into account makes it possible to improve the solution for the flows with low dynamic nonequilibrium for which the first-approximation models are justified. It is preferable to use two-temperature flow models under the conditions of high dynamic nonequilibrium.
