A Quantitative Determination of Minimum Film Thickness in Elastohydrodynamic Circular Contacts [PDF]
Tribology Letters, 2021 Abstract The current work presents a quantitative approach for the prediction of minimum film thickness in elastohydrodynamic lubricated (EHL) circular contacts. In contrast to central film thickness, minimum film thickness can be hard to accurately measure, and it is usually poorly estimated by classical analytical film thickness formulae. For

Slot coating minimum film thickness in air and in rarefied helium [PDF]
Chemical Engineering Science, 2016 Abstract This study assesses experimentally the role of gas viscosity in controlling the minimum film thickness in slot coating in both the slot over roll and tensioned web modes. The minimum film thickness here is defined with respect to the onset of air entrainment rather than rivulets, the reason being that rivulets are an extreme form of ...

Analytical Formula for the Ratio of Central to Minimum Film Thickness in a Circular EHL Contact
Lubricants, 2018 Prediction of minimum film thickness is often used in practice for calculation of film parameter to design machine operation in full film regime. It was reported several times that majority of prediction formulas cannot match experimental data in terms ...

Structural Design and Lubrication Properties under Different Eccentricity of Magnetic Fluid Bearings
Applied Sciences, 2022 As a lubricant, the viscosity of the magnetic fluid changes with the external magnetic field, which improves the bearing capacity of the oil film and hence the lubrication effect, and has a promising application in bearings.
