Abstract

A derivation of the "exact" two-point equations analogous to those used as a\nbasis for one-point Reynolds-Averaged Navier-Stokes turbulence model for\nvariable density, incompressible turbulence. The purpose is to present the\nstatistical correlations that must be dealt with to yield a two-point, or\nalternatively, a spectral model of variable density turbulence.\n
