N2 - To verify and confirm the credibility of the numerical results of two-dimensional shock wave/laminar boundary layer interaction, the credibility of numerical results was evaluated using wall-surface criteria. It is proved that, for 2D compressed flow, the wall-surface criteria matches analytical solution of NS equation near the wall. While it is found that the solution of numerical simulation using OpenCFD meet wall-surface tangential momentum criterion and energy criterion better with the more fine grids, but does not meet wall-surface normal momentum criterion because of the ill-suited wall pressure boundary condition. It shows that wall-surface criteria might be a kind of method to verify the CFD numerical computations of near-wall flows and the criteria standard should be studied further.
