A FINITE DIFFERENCE METHOD SOLUTION OF NONSIMILAR, EQUILIBRIUM AND NON- EQUILIBRIUM AIR, BOUNDARY LAYER EQUATIONS WITH LAMINAR AND TURBULENT VISCOSITY MODELS. PART II: COMPUTER PROGRAM AND SUPPLEMENT

Abstract

This report describes a program for the numerical solution by an explicit finite difference technique of the momentum, species conservation, and energy equations for an equilibrium or chemically reacting air boundary layer. Laminar and several turbulent viscosity models can be applied through the thickness of the boundary layer. Seven air species are included: O2, O, N2, N, NO, NO+ and e-. Laminar and turbulent effects in any of the equations can be selectively controlled by input indicators. The various viscosity models can be applied to the entire thickness of the boundary layer or the boundary layer can be divided into two segments and different viscosity models applied to each segment. Provision has also been made for boundary layer swallowing of new inviscid streamlines. Properties along the inviscid streamline are computed to establish the varying streamwise outer edge conditions. (Author)
