Nonequilibrium boundary layer flows of burned gas mixture
Abstract
An implicit finitedifference method is applied to the solution of the governing equations for the twodimensional steady flow of burned gas mixtures of N species with chemical reactions along a flat plate, forming a laminar or turbulent boundary layer. The calculation technique uses a nodal network with a varying step size in the xdirection for both laminar and turbulent flows, and a constant step size in the ydirection for laminar flows and a varying step size for turbulent flows. The concentration distributions in laminar flows are effectively controlled by the multicomponent diffusion process in addition to the direct effect of chemical reactions. In turbulent flows, the concentration distributions are likely to be uniform across the layer because of the turbulent motion of the flows, and are effectively controlled by the multicomponent diffusion process in the region close to the wall.
