Electrohydrodynamics (EHD) studies the interplay of mechanical and electrical forces in fluids |1–4|. In a first approximation it is assumed that electrical currents are very weak and therefore magnetic effects are negligible. Maxwell’s equations are then reduced to Gauss’ law and the charge conservation law. If a thermal gradient is added to the system interesting new phenomena appear, which may completely modify the previously existing EHD effects. In fact, the combined action of an electric field and a thermal gradient have long been studied with the aim of enhancing the heat transfer between metallic boundaries |5–7|.
