Wave/Current Induced Forces on Circular Cylinders.

Abstract

The numerical simulations of oscillating plus mean flow past a circular cylinder have been carried out in detail through the use of a commercially available software produced by CFDRC, running on a Silicon Graphics Inc. Indigo 2 Extreme computer. The Reynolds number, Keulegan Carpenter number, and relative current velocity were systematically varied. Sensitivity analysis was performed to delineate the effects of time step, turbulence model and numerical schemes. The results have been compared to those obtained experimentally and to those predicted by the Morison Equation. In many cases the predicted force coefficients have shown good agreement with those obtained experimentally.
