Simulation Research on Trapped Oil Pressure of Involute Internal Gear Pump [PDF]
Mathematical Problems in Engineering, 2021 The main structure of an internal gear pump consisted of an internal gear pair, including an internal gear and an external gear. The internal gear pump had oil trapping phenomenon like other hydraulic gear pumps. In order to solve the oil trapping phenomenon of involute gear pump with internal meshing tooth profile, in this paper, the mathematical ...

Electrowetting-Induced Oil Film Entrapment and Instability [PDF]
, 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.
