A simplified spectral closure for homogeneous turbulence Application to the boundary layer
Abstract
A turbulence model is proposed for the prediction of inhomogeneous flows. A spectral closure is used to predict the energy transfer to the dissipative scales. The inhomogeneous transport terms are evaluated within the framework of one-point closures. Rough approximations are made concerning the anisotropy of turbulence. In the case of a flat plate boundary layer, the model is found to compare favorably with the experimental data. Possible improvements are discussed.
