Disjoining Pressure Isotherms for Oil−Water−Oil Emulsion Films

Langmuir, 1997
We have used a novel liquid surface forces apparatus (LSFA) to determine the variation of disjoining pressure with film thickness for dodecane−water−dodecane emulsion films. The LSFA allows measurement of film thicknesses in the range 5−100 nm and disjoining pressure from 0 to 1500 Pa. Disjoining pressure isotherms are given for films stabilized by the

Measurement of Oil Film Pressure in Piston Pin-Boss by Thin-Film Pressure Sensor

SAE Technical Paper Series, 2015
<div class="section abstract"><span class="label">1</span><div class="htmlview paragraph">Piston design approach for automotive engines has been advanced from both experimental and calculation analysis. However, the developments of experimental analysis method that can verify the accuracy of the calculation analysis are required.

Rheology of Oil Films at High Contact Pressures

Nature, 1972
WE report here a new approach to studying the shear behaviour of thin films of oil under conditions of elastohydrodynamic lubrication such as arise at points of contact in ball bearings or between gear teeth. During its passage through the contact the oil is rapidly compressed to pressures in the region of 104 bar and then sheared by the sliding motion

Pressure Distribution in Oil Films of Journal Bearings

Journal of Fluids Engineering, 1932
Abstract One fact which is becoming widely recognized by users of journal bearings is that under proper conditions of operation the load applied to a journal bearing is supported by the hydrostatic pressures built up in a film of lubricant wedged between and completely separating the journal and bearing.
