Wave power extraction by arbitrary arrays of non-diffracting oscillating water columns

Abstract

A model to predict wave power conversion from arbitrary arrays of oscillating water columns is presented. Based on linear potential theory and idealized non-diffracting machines, it relies on a published analytical solution for the flow field generated by a single oscillating pressure patch on the ocean surface. Estimates of wave power conversion are obtained for several array configurations and well-defined wave resources at two sites in Hawaii, using a single-processor computer. Such results illustrate the versatility and computational efficiency of the model. The proposed approach allows a relatively easy evaluation of interferences among individual machines. This would be useful in optimizing the spatial arrangement of oscillating water columns in large wave farms.

Wave power extraction by arbitrary arrays of non-diffracting oscillating water columns is located in Hawaii, United States of America.
