在CFD模拟中，松弛方法被广泛用于数值波浪水池(NWTS)中的吸波；然而，这种方法可能非常昂贵，因为NWT的一部分必须专门用于松弛区域。在这篇简短的技术说明中，报告了一项关于松弛方法对吸收不同类型波的影响的参数研究。此外，还对松弛法提出了一个简单的修正。结果表明，改进的松弛方法有助于将松弛区域的长度缩短近一半，同时保持了良好的吸波性能。
In CFD modelling, relaxation methods are widely used in numerical wave tanks (NWTs) for wave absorption; however, this method can be very expensive as part of the NWT must be dedicated to a relaxation zone. In this short technical note, a parametric study on the effects of the relaxation approach on absorbing different types of waves is reported. In addition, a simple modification to the relaxation method is suggested. The results appear to show that the modified relaxation approach helps to reduce the length of the relaxation zone by nearly half whilst retaining good performance in terms of wave absorption.
