The calculation of chemically reacting turbulent boundary layers by means of finite chemical kinetics
Abstract
A computer program developed at Delft University of Technology to describe twodimensional turbulent flows through channels with and without sudden expansion was extended by accounting for heat and mass transfer at the boundaries. The wallfunction method of Chieng and Launder (1980) was adapted, allowing the calculation of the Von Karman constant E, which is a function of the local boundarylayer structure in the case of mass transfer. A finitechemicalkinetics combustion model was implemented in this computer program. The equations for the mass fractions are solved in two steps. In the first step the convection and diffusion of mass fractions is accounted for. In the second step chemical reactions are taken into account by integrating the chemical source term with the integration method for Gear (1971) at each gridpoint in the flow domain. Results of calculations are presented.
