Abstract
In order to evaluate manoeuvrability of ships in its design phase, hydrodynamic forces and moment acting on the ships in manoeuvring motion must be estimated. Authors are working for developing a computer program using CFD (Computational Fluid Dynamics) technique for calculating hydrodynamic forces and flow filed around ships in manoeuvring motion. In order to develop reliable CFD codes, experimental data are needed for its validation. Authors having had so far reported such kinds of experimental data for bare hull condition carried out tank test for obtaining experimental data for conditions with a propeller and a rudder. Stern flow field of a tanker ship model is measured using an 8-hole Pitot probe which detects three dimensional velocity components. Effect of rudder angle and propeller revolution together with oblique angle and turning rate on flow field around the model ship in manoeuvring motion is clarified experimentally. Uncertainty analysis is also applied to the measured data and validity of the test data is examined.
