Abstract

The paper considers the problem of high-velocity flow past a perfectly sharp edge. The solution was carried out using the model kinetic equation for polyatomic gases and the Navier–Stokes–Fourier model. The method of solving the problem is described. The distribution of gas parameters is calculated on the plate surface and above it. Gas parameters are analyzed near the sharp edge. The Navier–Stokes–Fourier model application area for the solution of this problem in terms of Mach numbers is evaluated.
