ABSTRACT
This paper examined the heat-transfer coefficients and the Nusselt number for turbulent flow for a methane-air flame occurring in cross-flow streams in an open duct. The governing equation of momentum, energy, mass fraction and radical nuclei concentration were solved in a fully coupled fashion at each control volume. The model encompasses conservation equations of gas components participating in the process and energy equation. A FORTRAN code was written with a Tridiagonal matrix solver (TDMA) used to obtain the temperature, velocity and particulates profiles on the flat plate. The Nusselt number for the flow was calculated and plotted as a function of the calculated Rayleigh number. It was observed that a curve obtained with temperature and pressure far from the critical region approaches the line obtained with a classic correlation.
