On the Numerical Simulation of Turbulent Flows in Complex Geometries

Abstract

A solution methodology for the numerical simulation of turbulent reacting flows in geometries described by general curvilinear coordinates has been developed. The method is based on the solution of Favre averaged variables. A k-epsilon turbulence model with wall functions has been used to close the governing equations. Models for turbulent diffusion and premixed flames have been incorporated into the solution method. The numerical solution of the governing equations is accomplished by solving for the Cartesian velocity components on a non-staggered grid. An evaluation of the solution methodology is presented.
