Abstract: Interaction of two supersonic parallel uniform rarefied streams separated by smooth semiinfinite plane plate is studied past the trailing edge under condition the equality of a pressure in undisterbed flows (tangential discontinuity). Analysis is based on a kinetic equation which is solved numerically by finite difference method. Special attention is paid to the cases: 1) simple tangential discontinuity (discontinuity in flow velocity with both density and temperature being constants) and 2) contact discontinuity with equal velocities of undisturbed streams. Any case of discontinuity generates waves traveling from the plane of the plate. At a large distance from the trailing edge thе solution of the kinetic equation is close to the solution of the corresponding parabolizedl Navier–Stokes equations.
