Optimization of Ion Migration During Lithium‐Ion Recovery Through Electrodialysis by Numerical Simulations

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Electrodialysis plays an important role in lithium extraction from brine. A two‐dimensional mathematical model for steady electrolyte transport during electrodialysis desalination is constructed in this study to uncover the mechanism of lithium‐ion transfer and forecast the behavior of electrodialysis.

A Reynolds Stress Closure for Compressible Turbulent Flow

open access: yesJournal of Applied Fluid Mechanics, 2011
Several studies of compressible flows show that the pressure-strain is the main indicator of the structural compressibility effects. Undoubtedly, this term controls the change in the Reynolds stress anisotropy. Regarding the model of Adumitroiae et al.,

A critical comparison of several low Reynolds number k-epsilon turbulence models for flow over a backward facing step [PDF]

open access: yes
Turbulent backward-facing step flow was examined using four low turbulent Reynolds number k-epsilon models and one standard high Reynolds number technique. A tunnel configuration of 1:9 (step height: exit tunnel height) was used.
