| 摘 要： | 在２４０×１０５≤Ｒｅ≤５４０×１０５，２９４≤Ｋｃ×７８５，２５４×Ｌ／Ｄ×５０２的范围内实验研究了串列圆柱在规则波中迎浪前进时的波动压力、波动升力与波动阻力．实验模型由ＰＶＣ管加工制成，表面光滑．实验结果表明：在波流中，当Ｋｃ数较小而Ｒｅ数较高时，绕串列圆柱的流动与均匀流中的绕流有相似之处；随着Ｋｃ数和Ｒｅ数的增加，串列圆柱的柱间干扰效应会发生改变

| Abstract: | Fluctuating pressures, lift and drag of two circular cylinders in tandemarrangements wave investigated experimentally in this paper. The twocylinders, which were made of a PVC pipe and whose surfaces were smooth,were subjected to wave and current flow in the range of 2 40×10 5≤ Re≤5 40×10 5, 2 94≤Kc≤7 85, 2 54≤L/D≤5 02 . The results show that: the flow pattern around the two cylindersin wave and current flow are similar to those in uniform cross flow atsmall Kc numbers, but the interference ... |
