摘　　要：考虑到船舶实际营运过程中的营运剖面在船舶型线设计中的重要性,针对超大型液化气船,引入一种直立楔形艏部,分析其水动力特性并与传统球鼻艏进行对比,制定适用于工程设计的完整流程。采用势流软件结合自动优化平台进行自动优化,采用粘性流软件对优化后的线型进行计算对比,并在最后经过船模试验的验证。Nowadays it's a new trend for combining with the operational profile when designing a new hull form. A vertical wedge bow was designed for the very large gas carriers( VLGC). The hydrodynamic performance for this kind of bow was analyzed and compared with the traditional bulbous bow. A complete work flow adapted for practical application was made. The potential flow software was used to get a preliminary optimal solution; the viscous flow code was applied to carry out an advanced calculation and finally testify the result by tank test.
