Applicability of several free software tools for solving problems of compressible gas dynamics

Several free software tools are investigated for their applicability to solving problems of two-dimensional steady compressible gas dynamics. The following test cases are considered: inviscid flow in a channel with a central wedge and supersonic viscous flow past an axisymmetric double cone. Comparison of the results obtained using different codes with available experimental data and with results, obtained using in-house code developed at SPbPU, is performed.
