Abstract—A method for introducing artificial dissipation coefficients into a numerical algorithm based on the quasi-gasdynamic system of equations is proposed. The method applies to aerodynamic flows with large Mach and Reynolds numbers. Simulation results for the supersonic flow over the X-43 aircraft are presented as an illustration. The pressure distribution over the aircraft surface is obtained, which can be used to calculate the aerodynamic characteristics of X-43.
