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.
