Abstract: | 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 processors,
with the maintenance of the implicit type of a difference scheme in each subregion. The parallelization 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 scalability for a number of processors N ≤ 15. |
