A description of various program codes for the investigation of the viscous turbulent compressible gas flow around complicated configurations is presented. A series of test calculations for a tandem of 3D back-forcing and forward-forcing steps has been performed. The purpose of the calculations is to analyze the resolution accuracy of the separation zones using classical and modern methods. To achieve the goal, the physical features of the flow are described and the comparison of results obtained using different codes in the frame of back-forcing and forward-forcing steps tandem test case is done.
Keywords: supersonic flow, IDDES, tandem of steps, return flow, shock, separation point, attachment point, comparison of numerical and experimental results, accuracy.
Mots-clés : RANS, LES, rarefaction, compression
