摘　　要：为研究双喷水推进耦合条件下的操舵性能,本文选择某大型喷水推进装置为研究对象,基于两相流数值模拟方法,对不同航速下、不同操舵角度时单/双喷水推进操舵特性开展了数值计算,从流动特征和水动力性能角度探究了单喷水推进在不同舵角时的操舵特性以及双喷水推进耦合对操舵特性的影响。结果表明,单个喷水推进实际操舵力损失和操舵角度有关,和航速关系不大,损失主要由流体飞溅和方向舵本身设计引起;双喷水推进耦合操舵时,每个推进器操舵力优于单个喷水推进,转舵力矩也随之增加。In order to study the steering performance of double water jet propulsion,the steering characteristics and hydrodynamic performances of single/double water-jet propulsion at different ship speeds and steering angles have been got based on the two-phase flow numerical simulation method.The results show that the actual steering force loss of a single jet propulsion is related to the steering angle and has little relationship with the speed,which is mainly caused by fluid splashing and the design of the steering unit.The steering force of each propeller is better than that of single water jet,and the steering torque increases accordingly.
