Investigation of supercomputer capabilities for the scalable numerical simulation of computational fluid dynamics problems in industrial applications

Two main issues of the efficient usage of computational fluid dynamics (CFD) in industrial applications — simulation of turbulence and speedup of computations — are analyzed. Results of the investigation of potentials of the eddy-resolving approaches to turbulence simulation in industrial applications with the use of arbitrary unstructured grids are presented. Algorithms for speeding up the scalable high-performance computations based on multigrid technologies are proposed.
