摘要:

为实现船舶自航性能的快速预报,应用计算流体力学(CFD)方法,采用一种便捷的描述型体积力模型替代螺旋桨的作用,分别在无舵实船自航点和有舵模型自航点2种条件下对MOERI(Korea Research Institute for Ships and Ocean Engineering)集装箱船(KCS)的黏性自由面流场进行了数值模拟.依据等推力法、敞水计算和螺旋桨敞水曲线等,计算船体自航性能相关参数.计算结果与试验结果吻合良好.研究结果表明,使用描述型体积力法可以便捷而较为准确地预报船体自航性能.

Abstract:

In order to predict the self-propulsion quickly, based on the computational fluid dynamics (CFD) method, this paper performed numerical simulation of selfpropulsion for MOERI container ship(KCS) at ship point without rudder and at model point with rudder, in which the propeller was simulated by using a simplified prescribed body-force propeller model to give a model that determined propeller-hull interaction. The method to obtain self-propulsion factors was based on equality thrust method, open water computation and experimental open water curves. A comparison of calculated and measured data shows a fair agreement, indicating that the prescribed body-force propeller model can accurately and quickly predict the selfpropulsion.
