Abstract

A problem is considered for a flow past an infinitely thin plate installed at a zero angle of attack in a hypersonic flow. The NSF model is accepted as a physico-mathematical flow model. Calculations are made with the use of McCormack explicit scheme and Thomas algorithm. Two methods of boundary conditions setting on a solid surface are considered. It is shown that in the strongly non-equilibrium flow region application of the NSF model results in qualitatively incorrect results when calculating normal voltages.
