Parallelization algorithm for numerical solution of the two-dimensional stationary Navier–Stokes equations with use of implicit iterative scheme

For the case of perfect gas flow the parallelization is carried out of a computer code, developed for solution of the two-dimensional stationary Navier–Stokes equations with use of an implicit iterative scheme. The parallelization algorithm is based on the decomposition of a computation region into several parts according to the number of processors retaining the implicit type of the difference scheme in each subregion. As an example a supersonic flow past a sphere with account of its near wake is considered at $M_{\infty}=5$, $\operatorname{Re}_{0D}=10$ (laminar flow without recirculation region). A good scalability is obtained for the number of processors $N\le15$.
