A CALCULATION METHOD FOR THREE-DIMENSIONAL TURBULENT BOUNDARY LAYERS ON SHIP-LIKE BODIES

Since the boundary layer equations for the present case must be written in curvilinear coordinates, a procedure for calculation of metrics and curvatures for two coordinate axes must be available. This paper gives a brief description of such a procedure, which also includes streamline tracing, based on the Hess & Smith method for potential flow. The boundary layer equations are solved in their integral form, using empirical relations due to Mitchel et al. Cross-wise derivatives are taken into account in an iterative way, so the solution is not restricted to small cross-flows. The boundary layer on a ship model is used as a test case and comparisons are given with previous measurements by the author.
