The interaction between the oscillatory boundary-layer flow induced by Faraday waves and a sedimentary granular layer was studied in a Hele-Shaw cell vertically vibrated. The experimental parameters were the vibration frequency $f$ and acceleration $a$, and the particle diameter $d_p$. At a critical value for the depth of the supernatant fluid layer, $\Delta h_c$, it was observed a transition between a flat motionless granular layer and a second regime in which the granular layer undulates and oscillates periodically. For the smallest value of $d_p$ (for which the Stokes number was $St

法拉第波在Hele-Shaw池中诱发的泥沙运动

在垂直振动的Hele-Shaw单元中研究了法拉第波引起的振荡边界层流与沉积颗粒层之间的相互作用。实验参数为振动频率$F$ 和加速 $\mathrm{一种}$，以及粒径 $d_p$。在上清液层深度的临界值下，$\Delta H_C$，观察到平坦的静止颗粒层与第二种状态之间的过渡，在第二种状态下颗粒层周期性地起伏和振荡。对于最小值$d_p$ （其斯托克斯数为$ St
