Abstract

Work is in progress towards development of the "energy-pressure- velocity-scalar filtered mass density function" (EPVS-FMDF) as a new subgrid scale (SGS) model for large eddy simulation (LES) of high-speed turbulent flows. This is an extension of the previously developed "velocity-scalar filtered mass density function" method in low-speed flows. In EPVS-FMDF, the effects of compressibility are taken into account by including two addi-tional thermodynamic variables: the pressure and the internal energy. The EPVS-FMDF is obtained by solving its transport equation, in which the effect of convection appears in a closed form. The modeled EPVS-FMDF is employed for LES of a temporally developing mixing layer.
