| Abstract: | Using nonlinear, horizontal and two dimensional modified Lynett Liu model for internal long waves, we simulate the propagation process of small amplitude solitary waves going into and out of the tank outlet, and the diffraction through the narrow tank. By analyzing the variances of the vertical profiles of solitary waves and the form of horizontal two dimensional wave patterns with the shape of the tank outlet and the width of the open fluid area, we investigate the lateral boundary effects on the propagation of solitary waves. Meanwhile, we compared the simulation results with satellite images. |
