沿着一个几乎垂直的平板向下流动的油膜受到一个强大的法向静电场的作用。通过荧光成像测量稳态高度分布。当电极电位小于产生不稳定性所需的电位时，界面的二维响应<1%。与电场解耦合的流体高度的计算与低于稳定性阈值的电场的非耦合计算相同。还讨论了膜下压力分布和三维效应。
Thin films of oil flowing down a nearly-vertical plate were subjected to a strong normal electrostatic field. Steady-state height profiles were measured by fluorescence imaging. For electrode potentials less than that required to produce an instability, the two-dimensional response of the interface was < 1%. Calculations of the fluid height coupled with the electric field solution were identical to uncoupled calculations for electric fields below the stability threshold. Pressure profiles under the film and three-dimensional effects are also discussed.
