Description
Summary:Based on a compact version of the hyperbolic system of quasi-gas-dynamic equations, a numerical algorithm for unstructured meshes is developed and implemented on modern multiprocessor K-100 and K-60 computing systems (Keldysh Institute of Applied Mathematics, Russian Academy of Sciences). The flows around the model of a high-speed aircraft at the Mach number M = 6 and different angles of attack are calculated. Numerical modeling of an unsteady flow in the air intake channel is carried out.
