| Abstract | This paper describes procedures and methodologies that were recently developed to enhance the capabilities of an in-house time-domain panel method code, Propella. This non-uniform inflow, potential-flow based solver now has the capabilities of predicting the hydrodynamic characteristics for a propeller-nozzle-rudder assembly and for partially cavitating propellers under arbitrary cavitation numbers. An automated propeller spatial geometry and surface mesh generator and a 3D unsteady CFD visualization component as a pre- and postprocessor using object-oriented technology with MFC and OpenGL were also developed. Loads for both propeller-nozzle-rudder assembly and a cavitating propeller-nozzle-rudder assembly and a cavitating propeller-nozzle-rudder assembly and a cavitating propeller were presented. Comparison of the integrated values Kt and Kq with experiment was made. Comparisons showed agreements with the measured ones. |
