Parallel numerical method of solution of Navier-Stokes equations for large eddy simulation of turbulent flows
E. A. Danilkin, A. V. Starchenko
Parallel implementation of algorithm of numerical solution of Navier-Stokes equations for large eddy simulation (LES) of turbulence is presented in this research. The Smagorinsky model is applied for sub-grid simulation of turbulence. This model with numerical Van Leer’s scheme for advection terms provides good agreement with experimental data. Various ways of geometrical decomposition for parallel numerical solution of transport equations are investigated. A theoretical analysis of parallel algorithms effectiveness was performed and recommendations for their application were developed. Special techniques like the order of nested loops and the effect of cash memory are applied to increase performance of the developed parallel programs.
