EXPERIMENTAL AND NUMERICAL STUDY ON WAVE RUN-UP

Abstract

Wave run-up with a single cylinder and with various distances between two cylinders is investigated. In order to measure and analyze the wave run-up around the cylinders, the experiments were performed in a two-dimensional wave flume. For the experiments, circular, square and 45-degree rotated square cylinders in single and tandem arrangement were tested with regular waves in six wave periods and four wave slopes. The measured data of the first-order harmonic components was compared with analytic solutions and commercial software (Hydro-Star). It was shown that the wave run-up generally tended to be close to the analytic and numerical solutions even though there were some variations in magnitude. Furthermore, the effect of the distance between two cylinders was analyzed.
