| 摘 要： | 基于数值波浪水池技术,对波浪中高速三体船运动及增阻进行CFD计算研究。控制方程—RANS方程和连续性方程使用有限体积法离散,非线性自由面采用VOF方法处理;在入口边界模拟柔性造波板运动产生入射波,使用位于波浪水池尾部的人工阻尼区消波。首先对规则波顶浪中单个主船体的运动和增阻进行了计算,并与高速细长体理论计算结果进行了比较;随后进行了三体船运动和增阻计算,分析了侧片体对主船体阻力增加的影响。为高速三体船耐波性研究提供了数值工具。

| Abstract: | Some research work on CFD computation of ship motions and added resistance in waves for a high speed trimaran is carried out in this paper.The governing equations,Reynolds Averaged Navier-Stokes (RANS) and continuity equations are discretized by finite volume method(FVM).Volume of fluid(VOF) method is adopted to deal with the nonlinear free surface.The incident waves are generated from the inflow boundary by prescribing a velocity profile resembling flexible flap wavemaker motions,and the outgoing waves are... |
