AN EXAMINATION OF AXISYMMETRIC PROPELLER-HULL INTERACTION EFFECTS AND THEIR IMPACT ON THE DESIGN OF PROPELLER-VEHICLE SYSTEMS

A state-of-the-art computer program for directly calculating hull- propeller interaction effects by integrating currently available numerical models is introduced. Called APHIPS (Axisymmetric Propeller-Hull Interaction Program System), the program employs a boundary-integral model for the axisymmetric potential flow about the vehicle hull, a finite-difference model for the axisymmetric boundary-layer flow along the hull and a full three-dimensional boundary-integral model for the calculation of the potential flow through the propeller. These three flow models interact, and the solution of each modifies the solution of the other two. The final equilibrium achieved represents the flow solution about the hull- propeller system with all the interactions taken into account. The APHIPS program is employed to predict the interaction of the hull and propeller flows about bodies for which experimental measurements exist. The results of the numerical calculation are compared with the experimental findings for validation, and the agreement is found to be good. Preliminary investigations into the nature and magnitude of the flow interactions are also performed. Examination of these results indicates that the interactions can be quite significant and can therefore have a large impact on the design of propeller-vehicle systems.
