摘要
Based on planar motion mechanism and overlapping mesh technique, the maneuverability hydrodynamic derivative of KVLCC2 ship model in viscous flow field is calculated. By numerical simulation of oblique shipping motion, pure sway motion and pure yaw motion, the calculated hydrodynamic force is compared with the experimental value under corresponding conditions. The calculated hydrodynamic derivative is in good agreement with the experimental value, and the accuracy of the calculated hydrodynamic derivative is high. On this basis, the trim is added to the ship to study the variation law of hydrodynamic derivative of ship maneuverability under the condition of trim.
