Implementation the low Mach number method for calculation of flows in the software package NOISEtte

The work is devoted to the development of computational techniques for simulating flows with low Mach numbers on unstructured meshes based on the Roe method and the edge-based vertexcentered higher-accuracy schemes. The techniques have been implemented in the in-house code NOISEtte. The results of predictions of inviscid compressible flow over NACA0012 airfoil with low Mach numbers are presented and analyzed. The computations are performed on structured and unstructured triangular grids.
