A supersonic flow past a finite flat plate at zero angle of attack is considered. Numerical simulation of the problem is conducted using Direct Simulation Monte Carlo (DSMC) method, relaxation-type model kinetic equations and Navier-Stokes equations with velocity slip and temperature jump boundary conditions. Limits of applicability of the continuum approach and the approach based on solving of the model kinetic equations are studied. It is shown that a strong non-equilibrium flows at high hypersonic speeds leads to the fact that the Navier-Stokes equations can not even qualitatively correctly predict the behavior of the main flow variables near the plate. At the same time, the approach based on solving of the model kinetic equations demonstrates good agreement with the DSMC data under all considered conditions.
