Abstract

The magnitudes of the terms in the evolution equation for the single-point, scalar, joint concentration probability density function (PDF) are approximated using direct numerical simulation (DNS) results for a two-dimensional, compressible, turbulent, reacting, mixing layer, at a convective Mach number of 0.2. The results from the current study suggest that for low to moderate Reynolds number flows the lateral advection term, the turbulence-enhanced diffusion terms, and the reaction terms seem to be the dominant terms in the PDF equation.
