Abstract
In order to develop a calculation method using CFD, computational fluid dynamics, for estimating the hydrodynamic forces and moment acting on ships in manoeuvring motion, experimental data are needed for its validation. Especially, experimental data of flow fields around ships in manoeuvring motion are crucial for developing an advanced CFD code. In this paper, stern flow field data of a container ship model, equipped with a rudder and a propeller, measured by using an 8-hole Pitot probe are reported. The data clearly show wake distributions and vortices shed from the model ship hull in turning motion with oblique angle. The effects of turning rate on the wake and vorticity distributions are discussed. Uncertainty analysis results of the measured data are also presented and validity of the test data is examined.
