Abstract
An explicit finite-difference technique has been developed and applied to solve the governing partial differential equations for the three-dimensional incompressible turbulent boundary layer. The method uses a mixing-length concept suggested by Prandtl for representing the turbulent shear stress tensor. The only empirical input is a mathematical model for the mixing length taken after Maise and McDonald which incorporates the van Driest damping factor in the near-wall flow region. The predicted boundary-layer parameters and the velocity profiles agree well with the experimental data for two geometries considered, bom of which contained a plane of symmetry with large transverse gradients in flow properties to provide a severe test of the method of solution and to a lesser extent the shear model. The analysis does not indicate a collateral near-wall layer as suggested by several experiments.
