摘要：

An analysis is made to find the transport properties of a free turbulent flow using an entity model previously shown to have good prediction capability for pipe flow. It is shown that the double structure of the turbulent eddies and the anisotropic shape of the larger eddies can be satisfactorily incorporated into the model without undue complexity. The analysis results in expressions for the various diffusivities in terms of properties of the turbulence. Predictions can be made for the diffusivity ratios and their dependence on molecular properties of the fluid determined. The results are shown to be in good agreement with the available experimental data. © 1969.
