Sažetak
Rudders located in the stream accelerated by the propeller are prone to ventilation, which can undermine the turning ability of the vessel due to the loss of the rudder lift force. Such multiphase flow is a complex phenomenon, which is hard to numerically predict and control. The aim of this study is twofold. Firstly, the RANS-FVM is validated by simulating flow around the rudder with a high angle of attack and comparing the results with the experiments. Secondly, the rudder with fences is numerically analyzed under the same conditions in order to try to suppress the ventilation, which was found to be a successful technique.
