An Analytical Solution of the Compressible Laminar Momentum and Thermal Boundary Layers with Pressure Gradient and Continuous Mass Injection

Abstract

The study describes an analytical solution of the nonsimilar laminar boundary layer with pressure gradient, variable wall temperature and continuous injection. The method consists of transforming the partial differential equations for momentum and enthalpy and then solving the transformed equations by assuming polynomial stream function and enthalpy profiles. Solutions obtained show very good agreement with exact numerical results. The solutions are obtained for flows over wedges as well as at the two-dimensional stagnation point and over curved surfaces of a two-dimensional body in crossflow. The results of the study show that the boundary layer is very strongly effected by the injection mass flow rate.
