摘要
论文采用基于RANSE的数值波浪水池技术,开展短波中顶浪航行船舶尾伴流场特性研究。以KCS船模为对象,进行了静水中尾伴流场的数值计算,通过与模型试验结果的对比分析,验证了数值计算方法;开展了不同波长规则波顶浪中船舶尾伴流场的数值计算,分析了波浪的影响,结果发现随着波长增大,时均轴向伴流分数总体上呈逐渐减小的趋势,论文对其成因机理进行了分析;最后,提出了规则波中时均轴向伴流分数变化传递函数的概念。
Some research work on the characteristics of wake field for KCS model advancing in regular head short waves was carried out by RANSE based numerical wave tank technology. Wake field for the ship mod- el in calm water was computed and compared with the experimental data to validate the numerical method. Numerical computations of wake field for KCS model advancing in regular head waves were carried out. The effect of wave on the wake field was analyzed. The results show that the time-averaged wake fraction will decrease in general while the wave length becomes longer; the mechanism of this law was analyzed. Finally, the concept of transfer function of time-averaged wake fraction variation in regular waves was put forward.
