Analysis of transient radiative cooling of a strongly radiating turbulent diffusion flame is described. The specific objective is to study the possibility of including realistic radiative cooling effects in transient simulations of turbulent reacting flows. The laminar flamelet concept is used to estimate all scalar properties other than temperature and density. These are obtained from transient evolutions for total enthalpy in conjunction with the state relationships. The equation is numerically solved in the mixture fraction-time space. Results show aflame structure involving a relatively cold soot layer on the fuel-rich side consistent with recent experimental data.
