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

Аннотация

This paper is devoted to the development of computational techniques for simulating low Mach number flows on unstructured meshes based on the Roe method and the edge-based vertexcentered higher accuracy schemes. The techniques are implemented in the in-house NOISEtte code. The results of predicting an inviscid compressible low Mach number flow over a NACA0012 airfoil are presented and analyzed. The computations are carried out on structured and unstructured triangular grids.
