| 摘 要： | 基于FLUENT软件对小水线面多体船舶进行了阻力特性研究。首先将计算得到小水线面双体船的粘性阻力与用经验公式估算得到的阻力进行比较,发现两者吻合较好;然后将小水线面双体船、三体船、四体船的阻力及流场分布进行比较,得到多体船的阻力特征;最后将静水中小水线面四体船的数值解与文献中的实验值进行比较,发现应用FLUENT软件计算小水线面四体船的阻力是可行的,验证了用FLUENT软件和相关参数设置计算小水线面多体船型阻力的正确性。

| Abstract: | This paper studies the resistance of small water plane multi-hull ships with FLUENT. Firstly, it compares the calculated viscous resistance of the SWATH with the resistance estimated by empirical formula. It shows that the results are in fair agreement. At the same time, the resistance characteristics of multi-hull ships are obtained from the comparison of the resistance and flow field distribution between SWATH,trimaran and tetramaran. Finally, the calculated resistance of the small water plane tetramaran is compared with experimental results from the literature. It is found that FLUENT is feasible to calculate the resistance of small water plane tetramaran, and the accuracy of the resistance of small water plane multi-hull ships calculated by FLUENT with relevant set-up is validated. |
