摘要
采用商业CFD软件FLUENT模拟了三体船周围的粘性流场,并考虑流体粘性及自由表面影响,数值预报了一艘三体船试验船模的阻力.计算中进行了2种不同侧体布置情况下船体周围流场细节的详细模拟,得到了相应情况下的船体总阻力,确定了合理的侧体位置.在此基础上,改变了侧体与主体横向间距进行了3种布置方案的相应计算,并进行比较,选取了最佳的侧体间距.通过计算结果与实验值进行的对比,验证了计算的可靠性,计算达到了船型优化的目的.
In this paper, the commercial computational fluid dynamics （CFD） software FLUENT was used to numerically simulate the viscous flow field around a trimaran＇s hulls in two cases with various side-hull layout, while taking free surfaces and flow viscosity into account. The detailed simulation of flow field around the hull and the to- tal resistances of hulls in these two cases were obtained. The proper locations for outriggers were determined. On this basis, more calculations were performed for three layout schemes with different lateral distance between outriggers and major hull. The most appropriate distance was decided. Also, comparative study between calculation results and experimental results was carried out to verify the reliability of calculation. The proposed research offers an effective optimization for the configuration of outriggers.
