摘要

The result of a computational investigation for an underexpanded jet and impingement on a wall with various distances from the jet exit is presented. The three-dimensional Navier-Stokes equations and a number of two-equation turbulence models based on the ω equation are computed. It is shown that the pressures on the impinging plate with the weakly nonlinear eddy viscosity model is in good agreement with the experimental data, particularly, in the case of occurrence of the stagnation bubble.
