摘要
利用FLUENT软件对圆柱周围等分布置6个小直径圆柱的流动问题进行了数值模拟。通过数值模拟,着重研究了附属圆柱直径及主从圆柱之间相对距离的变化对升力系数、拖曳力系数和涡脱落频率的影响作用。
The flowing problem about six identical small rods are uniform arranged in a circular cylinder surrounding is numerical simulated by FLUENT software.Through the simulation,the variations of lift coefficient,drag coefficient and vortex-shedding frequency with the diameters of small rods and distance between attached rods and main cylinder are investigated.
