Abstract

With rapid progress of computer technology, direct wave simulation techniques based on CFD (Computational Fluid Dynamics) have been applied to practical problems in coastal and/or port and harbor engineering. A numerical wave flume, which is considered one of the representative direct simulation techniques, has been expected to substitute for hydraulic model tests.In this paper, we consider characteristics of wave transformation on a reef, as one of the applications of the numerical wave flume to coastal structures. By observing its numerical results and comparing them with the experimental results previously obtained, we discuss its applicability to wave transformation on a reef.
