A solution algorithm based on fully coupled solution of the time-averaged Navier-Stokes equations is developed for the calculation of turbulent reacting flows. The governing elliptic partial differential equations are discretized by finite differences and the nonlinear algebraic equations are solved by a block-implicit algorithm employing Newton's method and sparse matrix techniques. Calculations have been made of a confined turbulent diffusion flame. Turbulence is represented by the k approx. epsilon model and chemical reaction is assumed to occur in one step at an infinite rate, controlled by the mixing of fuel and oxidant streams.
