Abstract

Internal waves in a stratified liquid propagate to fit the dispersion relation, depending only on the frequency and the angle to the gravity. The phenomenon of self-focussing of such waves is known as wave attractor. To study this phenomenon numerically or in a laboratory, it is common to use a wave-maker providing the forcing through one of the boundaries. In this work, we study the influence of the wave-maker forcing on the wave attractor formation and its characteristics.

造波器形状对波吸引子的影响

层状液体内波的传播符合色散关系，只取决于频率和与重力的夹角。这种波的自聚焦现象被称为波吸引子。为了在数值上或在实验室中研究这一现象，通常使用造波器提供通过其中一个边界的强迫。本文研究了造波力对波吸引子形成及其特征的影响。
