On the influence of a spatial grid structure on numerical simulation of a shock wave in a flow around 3D model
The influence of 3D spatial grid structure on a quality of the numerical modeling of viscous compressible gas flow at Mach number equal to 3 near a forward-facing part of a rectangular cylinder is demonstrated. The obtained results show that the grid structure produces critical ef-fects on the shape and the intensity of the head shock wave, which can exceed the influence of other numerical effects. The calculations are performed using a finite volume method imple-mented for regularized or quasi-gasdynamic equations.
