Summary:Parallel implementation of the algorithm of numerical solution of the Navier-Stokes equations for large eddy simulation (LES) of turbulence is presented in this research. The Smagorinsky model has been applied for subgrid simulation of turbulence. This model with numerical Van Leer’s scheme for advection terms is in good agreement with experimental data. Various ways of geometrical decomposition for the parallel numerical solution of the transport equations have been investigated. A theoretical analysis of the parallel algorithms effectiveness was performed and the recommendations for their application were developed. The parallel realization of the iteration methods for the numerical solution of the Poisson equation for velocity and pressure coupling are discussed. Special techniques such as the order of nested loops and the effect of cash memory have been applied to increase the performance of the developed parallel programs.
