Electrohydrostatic wetting of poorly-conducting liquids

The wetting behavior of poorly conducting fluids between two parallel conducting plates is studied, both, theoretically and experimentally. In the absence of an applied potential, the interface shape and height are determined by gravity and parameterized using the Bond number. In the presence of an electric field at sufficiently high values on the order of (1 kV/mm), there is modification of the interfacial stresses and liquid level. Here we measure the liquid level height as a function of the hydrostatic and electric Bond numbers.
