The two-temperature Navier–Stokes equations derived from an ellipsoidal Bhatnagar-Gross-Krook (ES-BGK) model for a polyatomic gas (Phys. Rev. E102, 023104 (2020)) are considered in regimes where bulk viscosity is much greater than the shear viscosity. Possible existence of a shock-wave solution for the steady version of these hydrodynamic equations is investigated resorting to the qualitative theory of dynamical systems. Stability properties of upstream and downstream equilibria are discussed for varying parameters.

Abstract The wave problem of perturbation propagation along an elastic pile interacting with the medium is investigated using the model of viscoplastic friction. An exact solution of the problem is obtained using the Laplace transforms for an arbitrary time of the loading period. The diagrams for velocity and stresses have been constructed.
