Surfactant micelles containing solubilized oil decrease foam film thickness stability
Journal of Colloid and Interface Science, 2014Many practical applications involving three-phase foams (aqueous foams containing oil) commonly employ surfactants at several times their critical micelle concentration (CMC); in these applications, the oil can exist in two forms: (1) oil drops or macroemulsions and (2) oil solubilized within the micelles.

Oil–Particle Separation in a Falling Sphere Configuration: Effect of Oil Film Thickness
Energy & Fuels, 2016High-speed videos of oil-coated solid spheres falling through an aqueous solution were analyzed to determine the amount of oil separated and the velocity of the coated sphere during free fall. The oil-coated sphere configuration is relevant to understanding the recovery of oil from oil sands; hence, bitumen was used as the oil phase.

Temperature compensation strategy for ultrasonic-based measurement of oil film thickness
Wear, 2021Due to non-destructive testing characteristics, ultrasonic-based measurements are regarded as potential strategies in real-time monitoring of varied lubricant film thickness for tribological systems.

Prediction of oil film thickness in trochoidal pump
Transactions of the Canadian Society for Mechanical Engineering, 2021A model for predicting the oil film thickness between the contact surfaces of the gerotor pump teeth is given in this paper. Gerotor pumps are rotary pumps with inner trochoidal gearing. The working process of the pump is followed by mechanical losses due to friction that occurs between the coupled surfaces. To reduce these losses and avoid wearing of

Interferometry-based measurements of oil-film thickness
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2001Measurement of the thickness of thin lubricant films separating rotating surfaces in elastohydrodynamic experiments presents some challenging problems. The nature of the experimental apparatus inhibits the use of most commonly applied interferometric phase measurement methods.
