Electrowetting-Induced Oil Film Entrapment and Instability [PDF]
Physical Review Letters, 2006 We investigate the spreading at variable rate of a water drop on a smooth hydrophobic substrate in an ambient oil bath driven by electrowetting. We find that a thin film of oil is entrapped under the drop. Its thickness is described by an extension of the Landau-Levich law of dip coating that includes the electrostatic pressure contribution.

Study of Flow between Non-Isothermal Disks in Hydro-Viscous Drive
Tribology Online, 2018 The film flow between the disks is the critical factor in the design of hydro-viscous drive. In the previous work dealing with the flow in the gap, few authors considered the effect of non-isothermal interface on the flow.
