... to optimize its operative performance, a semitheoretical model based on the principle of minimum energy is developed to predict the film rupture and wetting ability of the IL solution over a comprehensive range of IL mass fraction and flow rates. A first experimental validation of the fundamental equations...

...Guihui Ma; Fu Chen; Jianyang Yu; Huaping Liu Pressure-equalizing film is a slice of air layer attached to vehicle exterior with nearly uniform inside pressure, similar to ventilated cavity in composition; it is generated through exhaust process of the inside air chamber as vehicle emerges from deep...

..., the pressure at any given point even affects the deformation field on the opposite side of the bearing, resulting in increased computational times. Fig. 5 Sketch of the reference foil model The plot in Fig. 9 shows the resulting film thickness for all three foil models. As stated by Eq. (1...

...Mikhail Temis; Alexander Lazarev Mathematical model of oil flow in fluid film bearing in field of centrifugal forces is developed. Centrifugal forces for planet wheel bearing sliding surfaces and oil gap are formulated. This model is based on modification of two-dimensional Reynolds equation taking...

... of calculating the equilibrium position. The flow rate, fluid film thickness, and recess flow pattern are analyzed for various recess shapes. The CFD model is validated by published experimental data. The results show that the response surface model method is fast and robust in determining the rotor equilibrium...

... dominate acceleration forces; therefore, the latter are neglected. Cavitation Films If the gap of two narrow plates is filled with a viscous fluid, a fast separation of those plates requires a considerable force. This phenomenon is called fluid stiction or, if the fluid is oil, oil...
