Popis: The present work is dedicated to the behavior of an internal oscillating water column (OWC) under the external incidence of waves. The oscillation of the OWC is a subject of strong research interest since it can be applied to clean energy generation and also offshore exploitation. It is shown that the viscous effects are important so that the linear wave theory based on potential theory should be corrected. The paper discusses methods to achieve good results using panel method within potential theory and shows how to introduce the necessary correction. Both low-order and higher-order method are considered. The thin walls geometry of the specific OWC is challenging. The theoretical results were compared with experimental results using regular wave experiments and decaying tests with reduced scale models. The later was essential to get the viscous effects of the OWC.Copyright © 2013 by ASME
