THEORETICAL PREDICTION OF MIDCHORD AND FACE UNSTEADY PROPELLER SHEET CAVITATION

In this work, the linearized hydrofoil problem with arbitrary cavity detachment points is first formulated in terms of unknown source and vorticity distributions. The corresponding integral equations are inverted analytically, and the results are expressed in terms of integrals of quantities that depend only on the hydrofoil shape. The cavitating hydrofoil problem is then solved numerically by discretizing the problem into point source conditions at appropriately selected collocation points. Finally, the discrete vortex and source method is extended to predict unsteady propeller sheet cavitation with arbitrary midchord and/or face detachment.
