Abstract
A six metre long model of DREA's (Defence Research Establishment Atlantic) standard submarine model was tested in the National Research Council of Canada's NAE 9 x 9 metre wind tunnel. In these tests, oil flow visualization techniques were used to depict the streamline patterns of the flow over the submarine model for Reynold's Numbers based on hull length of up to 23 million. Various combinations of sideslip angle, and submarine configuration were tested. Results were recorded photographically and selected samples of the patterns are included in this report. The figures included depict the test setup, the development of a suitable system of boundary layer trips for the hull and appendages, and flow details over various portions of the submarine. The results provide qualitative information on the extent to which a two-strut mounting system affects the flow over the hull of the submarine model.
