Abstract

Abstract

The wave directional distribution has a significant effect on the wave propagation and its interaction with offshore structures. Most of the researches are based on unidirectional waves. In order to study the effect of directional distribution on the wave run-up on cylinders, a numerical modeling of multidirectional waves interaction with an array of cylinders was established based on the linear theory of wave interacts on an array of cylinders combined the method to generate multidirectional wave. A wave basin experiment was carried out, and the numerical calculation results were verified by the results of the physical experiment. The wave run-up around cylinders was calculated systematically, the results show that wave directional distribution has significant effects on wave run-up, and the effect is also based on the position around the cylinders. In the engineering design, if the calculation is based on unidirectional wave, it may underestimate or overestimate the wave run-up around the cylinders.
