用浸没边界方法模拟了两根柔性细丝在流动的肥皂膜中的运动，这是张等人实验研究的结果。[自然(伦敦)408,835(2000)]。我们在数值上发现了两个细丝持续振荡的两种不同模式：平行拍打和镜像拍打，这取决于两个细丝之间的距离。我们的模拟结果与实验结果至少在定性上是一致的，尽管模拟中流动的肥皂膜的雷诺数比实验低了两个数量级。
Using the immersed boundary method, we have simulated the motion of two flexible filaments in a flowing soap film, which was experimentally studied by Zhang et al. [Nature (London) 408, 835 (2000)]. We found numerically two distinct modes of sustained oscillation of the two filaments: parallel flapping and mirror-image clapping, depending on the separation distance between the two filaments. Our simulation results agree with that of the experiment at least qualitatively, even though the Reynolds number of the flowing soap film in our simulation is about two orders of magnitude lower than that of the experiment.
