Abstract
The report describes exploratory flow visualization experiments with an idealized submarine hullform in the Circulating Water Channel (Flume Tank) at the Marine Institute, St. John's, Newfoundland. The tests were static with variations of incidence angle and flow speed. Reynolds number was in the range 0.3 to 2.5 million based on hull length. Dye injection and air bubbles were used to visualize flow in the field off the model, and tufts and paint to determine limiting streamlines on its surface. The most effective technique was dye injection in the first case and paint in the second. The air bubble technique was not successful because large bubble size resulted in an excessive effect of buoyancy.
