Abstract

A simple mathematical model is presented for the prediction of the limiting bounds of the unmixedness parameter in non-premixed homogeneous reacting turbulence. This model is based on a Beta distribution for the PDF of a conserved Shvab-Zeldovich variable and generates statistical results which show similar trends to those previously obtained by computational experiments based on direct numerical simulations.
