The invention belongs to the technical field of ship design, and particularly discloses a rudder design method for avoiding cavitation denudation, which comprises the following steps: step S1, analyzing and evaluating the assembly mode of a false rudder and a rudder blade based on CFD simulation data, and determining that the top of the rudder blade is designed to be step-shaped; s2, performing memory comparative analysis on the flow data corresponding to the real ship with the same step and the CFD simulation data, and determining the size of a matched gap between a propeller and a rudder; rudder cavitation bubbles are avoided, and it is guaranteed that in the operation process of the ship, the using performance cannot be affected by the rudder cavitation bubbles.
本发明属于船舶设计技术领域,具体公开了一种规避空泡剥蚀的舵设计方法,包括以下步骤:步骤S1:基于CFD模拟数据分析评估假舵和舵叶的装配方式,确定将舵叶顶部设计为阶梯状;步骤S2:将同等阶梯实船对应的流动数据与CFD模拟数据记性比对分析,确定螺旋桨和舵之间相互配合的空隙大小;避免了舵空泡的产生,保证船舶在营运过程中,不会因为舵空泡的产生影响使用性能。
