Abstract

The interactions between turbulence and combustion are numerically examined. The effects of the combustion on the turbulence are studied by use of density-weighted (Favre) and density-unweighted (Reynolds) formulisms. The effects of the turbulence on the combustion are studied by use of the presumed probability-density-function (pdf) method, and three different forms of pdf: Double θ function, β function and clipped Gausian function are examined. Comparison results show that the choice of ensemble-averaging methods has greater influence on model simulation than the choice of presumed pdf forms.
