【摘要】 三体船构型复杂,主体与侧体间的兴波干扰影响因素较多,很难通过理论方法对其阻力性能进行准确预报。采用软件STAR-CCM+模拟三体船周围粘性流场,对一艘三体船模进行数值计算。计算中进行了侧体、主体以及三体船9种不同侧体布局详细模拟,求出了侧体与主体间的兴波干扰值,得到较佳的布局方案。通过计算结果与模型试验对比分析,验证了计算的可靠性。更多还原

【Abstract】 Trimaran has comparatively complex configurations with many factors influencing to wave interference between the main and side.It is difficult to forecast resistance performance accurately by theoretical method. Software STAR- CCM + was used to numerically simulate the viscous flow field around trimaran in this paper. Calculation has carried on a side, a main and trimaran’s hulls in nine cases with various side-hull layout and total resistance of trimaran in these cases, then the results of wave interference between main and side and better layout scheme were obtained. Comparative study between calculation results and experimental results was carried out to verify the reliability of the calculation.更多还原
