    Abstract

    Copyright © 2015 by the International Society of Offshore and Polar Engineers (ISOPE). In this study, a numerical wave tank is developed based on commercial software package FLUENT. Velocity inlet method is applied to simulate nonlinear wave groups and compared with 1st order and 2nd order wave theories. The horizontal particle velocity of the focused wave group and regular wave with identical crest height and trough-to-trough period were calculated. Main efforts are devoted to forces on a horizontal cylinder. The comparison of the vertical forces on horizontal cylinder for both nonlinear focused wave group and regular wave with the equivalent trough-to-trough period and wave crest amplitude is conducted. This simulation confirmed that the kinematics of focused wave group is much severe than that regular wave.
