An algorithm for numerical solution of Navier-Stokes equations for the two-dimensional motion of a viscous heat-conducting gas is proposed. The discretization of the equations is done using a combination of the method of trajectories for the substantial derivative and the finite element method with piecewise-bilinear basis functions for other terms. The results of numerical studies are presented for the structure of a supersonic flow in a flat channel in its step expansion zone for a wide range of Mach and Reynolds numbers. Velocity and pressure fields are investigated along with the vortex structure of the circulation flow in the domain after the step.
