Abstract : The frequency of eddies formed by and shed in the lee of bluff bodies in steady flow is well known, and to a lesser extent the associated 'lift' forces have been studied and are reasonably well understood. The problem is more complicated in oscillatory flows such as exists in water waves. Results of studies are presented for the case of a vertical circular cylinder which pierces the water surface. The value of the Keulegan-Carpenter number (NKC) in correlating the 'lift' forces with the flow and cylinder parameters is shown. (Author)
