  • The purpose of this study is to develop a tool for the analysis of the cavitating flow around trans-cavitating marine propellers. In this study, a linearized super-cavitation theory was applied in order to analyze the performance of the 2-dimensional foils. The numerical results correlated very well with experimental data. The trans-cavitating propellers, manufactured and tasted in KRISO, is selected to validate the lifting surface procedure. For a TCP with a Johnson's five term section, the comparison between the numerical prediction and experiments is fairly good and promising. The new lifting surface procedure, developed and validated with 2-D foils and a TCP, is generally considered applicable to the practical design of the trans-cavitating propeller with Johnson's five term section

  • In this study, a linearized super-cavitation theory was applied in order to analyse the performance of the 2-dimensional foils. For flat plate with non-thickness, the numerical results correlated very well with Nishiyama's theoretical results for closed cavitation model. For plano-convex section, the numerical results correlated very well with Wade's experimental data. The new lifting surface procedure, developed and validated in this study, is generally considered applicable to the performance analyses of the super-cavitating propeller and trans-cavitating propeller.
