Wake Structure, Loading and Vibration of Cylinders: Effects of Surface Nonuniformities and Unsteady Inflow

Abstract

The flow structure from stationary and oscillating cylinders, both with and without surface treatment, has been characterized in steady currents and waves using techniques of high-image-density particle image velocimetry. This quantitative imaging has led to new insight into the quasi-two-dimensional and three-dimensional features of the near-wake, which are intimately related to the loading on the cylinder, for cases where the cylinder is either stationary or elastically mounted. This program has resulted in a total of 46 publications in leading journals and the support of 15 graduate students.
