| 摘 要： | 数值波浪水槽技术是一种新兴的水波动力学数值模拟技术, 它能够实现水波现象的精确模拟。作为数值波浪水槽的一个重要功能, 消波技术被用于消除传入波浪在水槽末端的反射效应, 以防止反射波对有效实验区域的污染, 从而保证特定要求的水波实验的精确性。目前被广泛采用的消波技术可分为阻尼消波区和主动消波器两类。

| Abstract: | Based on the velocity invariability of the shallow water wave and using the shoaling effect,a unique active wave absorber for numerical wave lank is set up.This absorber's absorption parameter is contant,thereby make its mechanism very simple,When coupled with damping zone,it can achieve a perfevt wave absorption effect. By setting different absorption parameters and coupling with a damping zone,4 ISOPE wave absorption benchmark experiments are perhas excellent absorbency on deep water waves and limit depth waves,and when coupled with damping zone,it not only can absorb the wide spectrum nonlinear random waves but also shorten the length of the damping zone effevtively. |
