| 摘 要： | 采用CFD技术模拟了船池试验三体船型在不同速度下的粘性流场,计算中考虑了自由表面效应影响,数值模拟结果与试验结果进行了比较,然后在此基础上计算了侧体对应于不同纵横向位置时的9种三体船方案的总阻力.分析比较各方案的计算结果后,得出三体船阻力性能较优时侧体布局的一般规律,即侧体纵向位置变化对三体船静水阻力性能影响较大,当侧体横向位置不变,在较高速度时侧体纵向向后布置对阻力性能更有利.最后按阻力性能,从9种计算方案中得出优选方案.

| Abstract: | By using the commercial software CFX and the VOF method for the free surface,numerical simulation of the viscous free-surface flow around a model test trimaran was performed and comparisons were made between simulation and test.Then viscous free-surface flow around trimarans in model scale with nine different side hull position configurations was numerically simulated in the same way.The calculated resistance results were obtained,and the distribution of resistance curve relating the arrangement of side hul... |
