Abstract : The application of a theoretical method for predicting unsteady leading edge cavitation on two-dimensional foil sections with finite leading edge radii to the prediction of unsteady partial blade cavitation on marine propellers is discussed. The methods is used, together with the unsteady propeller lifting surface theory developed by Kerwin at MIT to predict partial leading cavitation on a propeller for which extensive model test data are available. It is concluded that the method generally predicts the occurrence and transient behavior of the blade cavities well. (Author)
