Turbulent boundary-layer flow computations with special emphasis on the near-wall region
Abstract
A boundary-layer flow model utilizing the k-epsilon closure and a special near-wall treatment has been developed to predict flow profiles under various conditions. The modified van Driest formula suggested by Cebeci and Chang (1978) is used in the near-wall region. Comparisons have been made with several sets of experimental data, including planar or axisymmetric, incompressible or compressible, laminar or turbulent, with or without blowing, reacting or nonreacting, and subsonic or supersonic flows. In most cases the computed results agree closely with the experimental data, indicating that the model with the present near-wall treatment is suitable for a wide range of boundary-layer flows.
