摘要：The wave diffraction from a box in a two-layer fluid was studied by time-domain approach. The Rankine source is used in the upper layer to establish the boundary equation. While the Rankine source and its images are adopted in the lower fluid. Through the construction of a function by velocity potentials of upper and lower velocity potentials on the internal surface, a single set of linear equations are set up to compute the time histories of wave forces and wave profiles by using a fourth-order Runge-Kutta method. The comparison results with other numerical method demonstrate the validity of this method. Copyright ? 2012 by the International Society of Offshore and Polar Engineers (ISOPE).
