Abstract : The streamline method for the determination of three-dimensional flow separation has been further exploited with emphasis on improving the friction model. Two approaches (numerical and analytical) for providing the required friction distribution are studied. The close agreement between the calculated line of separation based on numerical friction data and the original three-dimensional boundary-layer solution implies that the streamline method is a valid economical approach for determining the vortex-layer type flow separation if proper friction information is provided. The use of a simple analytical friction formula, on the other hand, only leads to qualitative results. (Author)
