Numerical simulation of compressible homogeneous turbulence
Abstract
Numerical simulation studies of compressible, homogeneous, turbulent flow were performed. The restriction of homogeneous turbulence allows periodic solutions and hence the use of fast Fourier transformations. Various time schemes were adapted to the Burger equation and then to the NavierStokes equations. A Fourier spectral method was used for the space discretization. Application in twodimensional (square geometry) and threedimensional (cube geometry) configurations are described. The simulation of flows with constant mean velocity field gradient was analyzed and applied to shear flow. Simulations where the initial velocity field is a superposition of a mean profile and a turbulent disturbanceapproximating a jet type flow are presented.
