Abstract

Experiments have been carried to investigate the effect of free stream turbulence on fluctuating lift forces and spanwise vortex shedding correlation of a circular cylinder at Reynolds numbers between 6x103<Re<4.6x104, and aspect ratio 0.25<L/d<11. Turbulence generating grids were used that produced a maximum turbulence intensity of 6.7% and a longitudinal length scale ranging 0.6<Λx/d<1.1. Attention is focused on the difference between small and large cylinder aspect ratio. The effect of oncoming turbulence was found to be larger at small L/d.
