| Abstract: | Macroscopic homogenized descriptions of reactive electrolyte transport through porous electrodes capture important sub-scale effects by the use of effective parameters, such as the dispersion tensor or the effective reaction rate. We apply the volume averaging method (VAM) to upscale the transport of electrolyte through periodic unit cells and evaluate the dependency and sensitivity of macroscopic effective parameters on pore-scale properties. The effective parameters can be applied in macroscopic cell models of redox flow batteries to study the effect of different pore-scale geometries within porous electrodes on the mass transfer rate or homogeneity of the electric current density. |
