ON THE COMPRESSIBLE COUETTE FLOW
RÉSUMÉ
Two exact solutions of Navier–Stokes equations for steady compressible gas flow are found when the viscosity coefficient is related to temperature by the Sutherland formula. The first solution describes the plane shear flow between parallel plates moving with different velocities (analog to the incompressible Couette flow). The second solution is related to the shear flow between coaxial cylinders moving along the common axis. In the solutions obtained, all gas-dynamic parameters are expressed by elementary one-variable functions. The compressibility effects on shear stress as well as the velocity and temperature profiles are investigated, including their qualitatively different configurations.
