... for controlling the air-cavity properties are needed. One of promising compact devices that can alter the air-cavity shape and size is a hydrofoil. In this study, a hydrofoil-equipped model-scale boat with a bottom recess for holding air was tested under adverse loading conditions in a water channel. States...

... of changing the cross-sectional shape of the moonpool recess was examined by comparing the predicted resistance of the original hull with the result of the model fitted with various moonpool configurations. The kinematics of the separated flow within the moonpool and downstream of the underside...
