| Abstract: | 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. |
