Stern Boundary-Layer Flow on a Three-Dimensional Body of 2:1 Elliptic Cross Section.

A comprehensive set of experimental data for flow over the stern of a three-dimensional model having 2:1 elliptic transverse cross sections, suitable for analytical comparisons, is presented. Included in this set are surface pressure and shear stress distributions, static pressure and mean velocity profiles, and Reynolds stresses. The eddy viscosity and mixing length values obtained from the measured Reynolds stresses and mean velocity gradients are also presented. The measured and derived data are compared with the predictions of existing three-dimensional theoretical methods. These comparisons confirm the need for improved prediction techniques in the thick turbulent boundary-layer region of the stern. (Author)
