主 题：Extreme waves vertical cylinder in-line wave force wave run-up
摘 要：In this paper,the interactions between extreme waves and a vertical cylinder are investigated through a 3-D two-phase flow *** numerical model is verified and validated by experimental ***,two factors are considered,the global wave steepness and the frequency bandwidth of the wave groups,in the studies of the in-line wave forces and the wave run-up around a *** is found that both the in-line wave forces and the wave run-up are remarkably increased with the increase of the global wave steepness,whereas the effect of the frequency bandwidth on the in-line wave forces is relatively weak in comparison with its effect on the wave *** minimum and maximum wave run-ups are located in the directions of 22.5°and 180°with respect to the direction of the incident waves,***,a new empirical formula is proposed for predicting the in-line wave forces by using only the free surface elevations around the *** results of the formula agree well with the simulation results.
