MEAN-FLOW MEASUREMENTS IN THE BOUNDARY LAYER AND WAKE OF A SERIES 60 C SUB B = .6 MODEL SHIP WITH AND WITHOUT PROPELLER

Results are presented from a towing tank experiment of propeller- hull interaction conducted to provide detailed documentation of the complete flow field appropriate for studying the flow physics and for validating computational methods. Mean velocity and pressure field measurements were made for the with- and without-propeller conditions for the Series 60 C sub B = .6 hull form. Surface pressure distributions and wave profiles were measured for both conditions. Resistance and self-propulsion tests were also conducted. An overview of the experiments is given, and some sample results are discussed to point out the essential differences between the flows with and without a propeller. The results are analyzed to assess the nature of the interaction between the propeller and the hull boundary layer and wake. To this end, use is made of a propeller performance program with both nominal and effective inflows. It is shown that most features of the interaction can be explained as a direct consequence of the propeller loading resulting from the propeller's three-dimensional, nonuniform inflow.
