【摘要】 为了分析双体高速客船实船螺旋桨、舵等附体的空泡剥蚀情况,在循环水槽开展船后螺旋桨模型空泡性能试验,针对实船常用工况开展船后螺旋桨、支架及舵等附体的模型空泡形态观察和空泡脉动压力测量,并结合实船勘验结果和数值仿真计算结果进行对比分析。分析结果表明全附体船模的空泡模型试验结果与实船勘验结果基本吻合,高速客船后螺旋桨根部在支架斜流后方很容易发生空泡,螺旋桨布置在支架后方过近,会造成螺旋桨的桨毂大端面出现空泡;常规的舵在高速船螺旋桨后方容易出现空泡现象,在舵的设计方面应该引起重视。更多还原

【Abstract】 In order to analyze cavitation erosion of the propeller and rudder of the high speed catamaran, the cavitation observation and pressure fluctuation measurement tests behind the ship are carried out in the CLCC. The tests results are compared with the actual inspection results for the real ship and the numerical simulation results. The analysis results show that the results of cavitation observation test are basically consistent with the inspection results for the real ship. If the propeller is placed too close behind the strut, cavitation of the large face of the hub of the propeller will occur. Attention should be paid to the design of the rudder, which is easy to cause cavitation problem for the conventional rudder behind the high speed ship.更多还原
