摘要：

A near-wall turbulence model based on kappa, epsilon, and <(upsilon(2))over bar> equations is described. It is used to predict flow and heat transfer in a two-dimensional channel and in boundary layers. Good agreement with data on skin friction, Stanton number, mean velocity, and turbulent intensities is obtained. Solutions to the model show the correct Reynolds number dependence without building it into any of the coefficients. Zero and adverse pressure gradient boundary layers are calculated; in both cases, the results agree well with experiment.
