Paper characterizes the hydrodynamic performance of a ‘flat plate’ Kaplan type propeller in axial cylinder at two different pitch settings, over a wide range of variable advance coefficients and at different cavitation indexes where cavitation is significant. The predictions obtained with a numerical boundary element method developed at DINAV, in terms of dynamic characteristics as well as cavitation extension are compared with the measurements taken in the cavitation tunnel of the same department on a model of 200 mm diameter. Main characteristics of the numerical panel method valid for cavitating ducted propeller are also provided in the paper.

Abstract
Paper characterizes the hydrodynamic performance of a ‘flat plate’ Kaplan type propeller in axial cylinder at two different pitch settings, over a wide range of variable advance coefficients and at different cavitation indexes where cavitation is significant. The predictions obtained with a numerical boundary element method developed at DINAV, in terms of dynamic characteristics as well as cavitation extension are compared with the measurements taken in the cavitation tunnel of the same department on a model of 200 mm diameter. Main characteristics of the numerical panel method valid for cavitating ducted propeller are also provided in the paper.
