Parallelization Algorithm for Implicit Method Computationof Hypersonic Nonequilibrium Gas Flow Past a Body, Basedon Navier—Stokes Equations

摘要

The earlier proposed algorithm of parallelization of the computer-code developed for solving the two-dimensional stationary Navier—Stokes equations using the implicit iterative scheme is extended to the nonequilibrium gaseous mixture flow. The parallelization algorithm is based on decomposition of the computation region into several parts corresponding to the number of proces-sors, with the maintenance of the implicit type of a difference scheme in each subregion. The paral-lelization efficiency is analyzed by the example of the computation of the flow past a re-entry vehicle moving in the Earth's atmosphere at a hypersonic velocity. The algorithm has demonstrated good scal-ability for a number of processors N ≤ 15.
