ABSTRACT
This paper proposes a numerical procedure to simulate a spatially decaying turbulence with constant time averaged properties.
A forced isotropic turbulence with statistically constant properties is generated thanks to a direct numerical simulation (DNS) in spectral space. Then, parts of this spectral DNS are used as boundary conditions for a finite difference DNS solver. The subsonic turbulent flow is injected at a very low convective mach number although fully compressible Navier-Stokes equations have been used. To evaluate the procedure, a planar turbulent premixed flame has been stabilized in a grid turbulence.
