Computer simulation of thick incompressible boundary layers

Experimental and numerical simulation results from examinations of thick laminar and turbulent boundary layer flows are compared, with attention given to the influences of various corrective functions in mixing-length models on the integral flow parameters. Governing equations are formulated for continuity, the distance along the wall, and the distance normal to a curved body surface. A turbulent flow version of the governing equations is defined and discretized for a rectangular grid. A solution is obtained with an alternating row and column pivoting strategy, which offers stability in the computations. Good agreement is demonstrated for computed and measured velocity distributions across a stern boundary layer in both the axial and radial directions.
