摘要:
目的 为了将高速与高耐波性能相结合,上海交通大学开发了高速穿梭艇系列复合船型,目前已发展出单体、双体和三体船型。 方法 介绍高速穿梭艇系列船型的新进展和船型设计特点,并通过数值水池实验对高速穿梭艇系列船型在静水中的直航性能进行研究。数值水池通过求解URANS方程和采用重叠网格技术来预报船体受力和运动。 结果 数值水池实验结果表明,高速穿梭艇系列船型具有优良的快速性和航行姿态,船体兴波和飞溅随船型的不同而有所差异。 结论 展示了多种创新的船舶设计方案,可为研究人员提供定量和定性的参考。 Abstract: SV-SJTU high-speed shuttle vessels are developed by Shanghai Jiao Tong University for fine seakeeping and high speed purposes. A series of SV-SJTUs have been developed, and are introduced in this paper. Straight forward CFD free running trials were conducted and the results are also presented. Hull resistance and motions are predicted by solving URANS equations and adopting the overset mesh method. The results of the straight forward CFD free running trials prove that SV-SJTUs have little resistance and fine hull motion in calm water, and their wave-making and splashing differ with different hull forms. This paper presents the designs of a variety of high performance ships, thereby providing quantitative and quali-tative references for researchers. -
