..., solvents, and solutes. It is referred to as the coffee stain ring effect. The phenomenon is caused by the outward microfluidic flow of the solute within the drop, which is driven by the evaporation of solvent. We show that the mechanism for the ring effect contributes to the nonuniform material removal...

...Guy Bayada; Sébastien Martin; Carlos Vázquez An average Reynolds equation for predicting the effects of deterministic periodic roughness, taking Jakobsson, Floberg, and Olsson mass flow preserving cavitation model into account, is introduced based upon the double scale analysis approach...

...Bogdan R. Kucinschi; Kenneth J. DeWitt; Mircea D. Pascovici A numerical model is developed to analyze the influence of thermal deformations on the performance of a radially grooved thrust washer. The analysis couples the flow phenomena (including cavitation) in the lubricant with the heat transfer...

The fluid motion within the thin film lands is governed by mass conservation and momentum transport...

...P. Hryniewicz; A. Z. Szeri; S. Jahanmir The objective of this study is to model fluid flow in grinding with nonporous wheels. While Part I focused on the flow in a simplified smooth geometry, in this part the wheel surface roughness is introduced. The applicability of the modified Reynolds equation...

Careful experimentation in a test SFD operating with controlled bubbly mixtures and freely entrained air evidenced similar physical behavior...

...Mihai Arghir; Jean Fre^ne It is well known that for a reduced Reynolds number Re * = ρ VH / μ s ˙ H / L greater than unity, inertia forces have a dominant effect in the transport equations, thus rendering the classical lubrication equation inapplicable. The so called “bulk flow” system of equations...
