摘要
文章将势流理论方法与波谱分析方法相结合,对浅吃水中高速排水型船舶的尾浪进行了数值计算,采用势流理论方法对船舶近域的波浪进行计算,将获取的部分波高数据(或试验数据)作为已知数据,采用波谱函数法进行分析求解,获取波幅谱函数,从而求解远域船舶的尾浪。文中采用试验数据对理论计算结果进行了验证,两者吻合较好。同时结合船模试验结果,探讨了水深、浮态等对单、双体船船舶尾浪的影响,该研究结果可为低尾浪船型的设计和优化提供参考。
In order to get the wash waves of passing ships in shallow water, a method that coupled a potential flow theory method with a wave spectrum method is used. The potential flow theory method is adopted as the stationary wave generation model that calculates the waves of ships in the near field; the waves calculated by the potential flow theory method in the near field are used as the input for the spectrum method which is used as the wave propagation model to simulate the waves of ships in the far field. Parts of the calculated results are validated experimentally, satisfactory agreement is demonstrated. The effects of water depth, afloat condition and configurations on wave making and wash waves of ships are investigated. The yielded results are reasonable and the near/far field com- bined method is applicable for the calculation of wash waves of ships, and it is significant for the optimization of hull form to design a lower wash ship.
