Abstract

The paper deals with PMM (Planar Motion Mechanism) test for ship models in CWC (Circulating Water Channel). Dynamic captive test in CWC has differences from test in towing tank. One of the different points is motion of model against the ground. In the case of test in CWC, the motion of model against the water is generated with the motion of PMM and flow velocity of CWC. The authors present the method of analysis for PMM test in CWC. And the comparison between data in towing tank and data in CWC is shown in the case of oblique towing test and pure yawing test. In order to check the blockage effect, oblique towing test is carried out with changing the setting position of a model in transverse direction in CWC. By the experimental results, PMM test in CWC using small model is shown to be effective.
