摘 要:为深入研究深V型船艉扰流板减阻机理,首先进行了深V型船艉扰流板系列减阻模型试验研究,获得了模型阻力减少4%左右的艉扰流板设计方案,该方案扰流板深度与艉板宽度之比为0.009 4;其次,采用RANS方程以及计及航态影响的数值计算方法,逐段分析了船体微段阻力变化规律。结果表明:扰流板减阻的主要原因在于其改善了船体航态,从而减少了压差阻力。In order to further investigate the deep-Vee ship equipped with stern interceptor resistance reduction mechanism, model tests of deep-Vee ship using the stern interceptor series for resistance lead to a stern interceptor design scheme by which deep-Vee ship model resistance reduces about 4%. According to the scheme, the ratio of the interceptor depth to stern breadth is 0. 009 4. Using the RANS and taking into account the influence of dynamic sinkage and trim, it is possible to analyze the rule of resistance change in every hull section. The results show that the resistance reduction of the interceptor is mainly due to the improvement of hull navigation state and the reduction of pressure resistance.
