Özet
In this paper, a new algorithm is developed to solve a two dimensional supersonic flow around a wedge-shaped airfoil. The MacCormackpredictor-corrector method is utilized to develop a solution. To further investigate the flow properties, a numerical algorithm written inC++ has been compiled so that it may be compared to commercial softwares. The developed algorithm is compiled and run with theinitial conditions of a free stream Mach number of 2 while the wedge angle is set at 15º. The compiled program revealed that the flowvelocities increased without bound. Adjustment of this condition was achieved by adding artificial dissipation. The addition ofdissipation term into the code resulted stable output and the presence of a shock. Same case was also simulated with ANSYS Fluentand CFL3D softwares using second order discretization.
