Prediction of Hydrodynamic Derivatives of KCS Based on Computational Fluid Dynamics

Abstract

Aiming at predicting the maneuverability of the ship in shallow water, KCS was selected as the research object. Static drift motion, pure sway motion, and pure yaw motion were performed to calculate the dimensionless hydrodynamic derivatives of KCS. A commercial software, STAR-CCM+ was used to simulate various kinds of movement conditions, by which the force and moment on the hull can be monitored. Then, through the curve fitting, hydrodynamic derivatives of KCS were predicted, and the maneuverability of KCS can be predicted.
