摘要

构造了一种改进的Hele-Shaw电池，该电池可以及时调制板隙。在各种频率下驱动板间隙时，观察到电池中空气和水之间界面上的高度非线性手指，但通常在60 Hz附近。推导了描述周期性驱动胞内流动的修正方程，并对波在圆形流体-流体界面上的线性稳定性进行了分析。

Fingering in a driven hele-shaw cell

A modified Hele-Shaw cell in which the plate gap can be modulated in time was constructed. Highly nonlinear fingers on the interface between air and water in the cell were observed as the plate gap was driven at a variety of frequencies, but typically near 60 Hz. Modified equations to describe the flow in a periodically driven cell were derived and the linear stability analysis of waves on a circular fluid-fluid interface was performed.
