摘　　要：应用FINE/Marine软件对某水线面大开口船舶阻力进行数值预报。计算船舶船舯开口开启和封闭状态下的船舶阻力及其运动参数,通过与模型试验的比较,探讨采用数值计算方法预报船舶阻力的可靠性;分析其流场变化,研究阻力增加的原因,为后续类似船舶设计提供阻力性能参考。结果表明:数值预报精度满足工程应用的需要,能够较好地模拟船舶周围流场的信息,大开口导致的粘压阻力变化是引起船舶阻力增值的主要原因。The numerical simulation software FINE/Marine was applied to predict the resistance performance of a ship with a notch.The resistance performance of the ship is simulated under the opening and closing of the notch to calculate the resistance and movement of the ship.The reliability of CFD used in the prediction is verified by comparing the calculation results with model test results.The change of flow field is analyzed,and the reason of the increase of the ship resistance is studied.The results show that the accuracy of the numerical simulation prediction meets the needs of engineering application and properly reflects the real information of surrounding flow filed.The change of the viscous pressure resistance caused by the notch is the main reason for the increase of the ship resistance.
