Investigation into the effectiveness of feed spacer configurations for reverse osmosis membrane modules using Computational Fluid Dynamics
TL;DR: In this paper, the authors used 3D steady state Computational Fluid Dynamics with mass transfer to compare four channels with feed spacer configurations (Ladder-type, Triple, Wavy and Submerged).

Diffusion coefficients and conductivities of alkylimidazolium tetrafluoroborates and hexafluorophosphates
TL;DR: In this paper, diffusion coefficients of alkylimidazolium tetrafluoroborates and hexafluorophosphates ionic liquids in water at room temperature were measured by the Taylor dispersion experiment.
Journal ArticleDOI
Investigations into the effects of mass transport and flow dynamics of spacer filled membrane modules using CFD
TL;DR: In this article, the authors investigated the effects of dimensionless filament spacing of feed spacer on flow and concentration patterns on membrane surfaces and found that spacers with higher SCE values would lead to higher mass transport of solute away from the membrane walls with moderate energy losses.

Measurement of Soret and Fickian diffusion coefficients by orthogonal phase-shifting interferometry and its application to protein aqueous solutions
TL;DR: A method to measure thermodiffusion and Fickian diffusion in transparent binary solutions and it was found that the former protein molecules are thermophilic and the latter thermophobic.
