Abstract : A predictive method for the titled flows based on the Prandtl energy method is developed and assessed by comparing prediction with experimental results. For constant density flows both gross properties such as spreading rate and maximum turbulent kinetic energy and detailed properties such as mean shear stress distribution are shown to be well predicted. For variable density flows considerable attention is devoted to the inclusion in the analysis of the added effect of pressure fluctuations and of the variation in the several extant empirical parameters on the turbulent kinetic energy.
