Abstract:

The 48-inch 121.92 cm diameter Garfield Thomas Water Tunnel of the Applied Research Laboratory was recently used to compare the relative cavitation characteristics of propellers operating on a surface ship hull. A basic objective of the investigation was to develop a method of using this facility for surface ship propeller evaluations. Evaluation of a propeller operated with a model hull in a water tunnel so that the three-dimensionality of the flow is maintained is one of several techniques of testing surface ship propellers. Although neither Froude nor Reynolds number scaling was applicable, it was demonstrated that meaningful cavitation results could be obtained if the flow conditions in the plane of the propeller matched those measured in towing tank tests where the effect of the free surface was present.
