Numerical simulation of high-speed air flows with high-temperature effects on graphics processor units

Research outputpeer-review

Abstract

Numerical simulation of shock wave phenomena in supersonic compressible flows with high-temperature effects is discussed. The finite volume method is applied to solve unsteady three-dimensional compressible Navier–Stokes equations on unstructured meshes. Hightemperature gas effects altering the gas dynamical processes are taken into account. Possibilities of the use of graphics processor units (GPUs) for the simulation of high-speed flows are demonstrated. Solutions of some test cases on GPUs are reported, and a comparison between
computational results of equilibrium chemically reacting and perfect air
flowfields is performed. Speedup of solution on GPUs with respect to the
solution on central processor units (CPUs) is compared. The results obtained provide promising perspective for designing a GPU-based software framework for practical applications.
