Phase-field modeling droplet dynamics with soluble surfactants [PDF]

, 2010
Using lattice Boltzmann approach, a phase-field model is proposed for simulating droplet motion with soluble surfactants. The model can recover the Langmuir and Frumkin adsorption isotherms in equilibrium.

Interfacial Heat Transfer of Condensation Bubble with Consideration of Bubble Number Distribution in Subcooled Flow Boiling

Journal of Thermal Science and Technology, 2013
For predicting the void fraction distribution in subcooled flow boiling, it is necessary to measure the interfacial heat transfer coefficient—which determines the amount of condensation rate of vapor bubble—with high accuracy.

Influence of material transition and interfacial area changes on flow and concentration in electro-osmotic flows [PDF]

Analytica Chimica Acta, 2013
This paper presents a numerical study to investigate the effect of geometrical and material transition on the flow and progression of a sample plug in electrokinetic flows. Three cases were investigated: (a) effect of sudden cross-sectional area change (geometrical transition or mismatch) at the interface, (b) effect of only material transition (i.e ...
