...A. Abouel-Kasem; F. A. Alturki; S. M. Ahmed In the present work, the topographical images of cavitation erosion surfaces at water and oil-in-water (o/w) emulsions were quantified using fractal analysis. The oil-in-water emulsion concentrations were 2, 5 and 10 wt. %, which are in the popular range...

...Sy-Wei Lo; Tzu-Chun Yang; Yong-An Cian; Kuo-Cheng Huang A model for oil-in-water emulsion has been developed in this paper. A group of viscosity coefficients transiting smoothly and incessantly from the thick film region to the thin film region is defined. The contributions from disperse...

...A. Abouel-Kasem; B. Saleh; S. M. Ahmed Wear particles produced by vibratory cavitation erosion tests on 1017 carbon steels in water and oil-in-water (o∕w) emulsions were analyzed. Scanning electron microscope (SEM) images of wear particles were acquired, forming a database for further analysis...

... these contribute to the user’s sensory perception, and thus appreciation, of the products concerned. In this paper, the lubrication properties of simple oil-in-aqueous phase emulsions are studied in a steel/elastomer “soft-EHL” contact. It is found that overall behavior is strongly dependent on the ratio...

...Haixia Yang; Steven R. Schmid; Ronald A. Reich; Thomas J. Kasun The lubrication mechanisms with oil-in-water emulsions have been extensively investigated based on the measurements of film thickness and/or tractions in the past few decades. However, direct observation of the emulsion flow, as a more...

...Ph. Boure´; D. Mazuyer; J.-M. Georges; A. A. Lubrecht; G. Lorentz The lubrication with oil-in-water emulsions is usually supposed to be governed by the oil phase being concentrated in a reservoir that supplies the contact. In this paper, another lubrication process in an elastohydrodynamic ball...

...A. Pereira; G. McGrath; D. D. Joseph The problem of predicting flow between rotating eccentric cylinders with axial throughput is studied. The system models a device used to test the stability of emulsions against changes in drop size distribution. The analysis looks for the major variation in flow...

...Steven R. Schmid; Jin Zhou Oil-in-water emulsions are widely used as lubricants/coolants in the ironing of beverage and food containers. This paper investigates this system, where the two phased flow problem presented by the emulsion is modeled using the Dynamic Concentration Theory of Wilson et al...

...A. Shirizly; J. G. Lenard Low carbon steel strips were cold rolled using various lubricants. The objectives were twofold. The first concerned whether the use of an emulsion would lower the loads on the mill as much as a neat oil would. The second was to study the effect of the lubricant...
