带首鳍斜支柱SWATH水动力的数值研究

Numerical simulation of hydrodynamic forces on a slant strut Small Waterplane Area Twin Hull with bow fins

该文是将CFD软件FLUENT用于带首鳍斜支柱SWATH粘性流场计算的一个尝试和探索性研究,重点在对有自由液面模型的研究。文中详细模拟了不带自由表面和带有自由表面的情况下有首鳍和不带首鳍,以及在带有自由表面的情况下首鳍0度攻角和5度攻角时SWATH周围的粘性流场,计算了其所受到的阻力和力矩,数值模拟与实验结果大体上吻合良好。

In this paper,the commercial CFD software FLUENT is used to simulate the viscous flow field around a canted-strut-SWATH with fins in the bow,and the total resistance and moment are calculated for several conditions,including the cases with or without free surface,the SWATH with and without fins,the fins with the attack angle 0 degrees and 5 degrees.Comparisons of the calculated results with experimental data show largely satisfactory agreement.
