Analysis of the prior art19demonstrates the development in 2011 of an all-alkaline PSA RFB system with alkaline-based oxygen(air) redox couple and a polysulfide redox couple, separated by an anion-exchange membrane (AEM). During the discharge process, shorter-chain-length polysulfides are oxidised...
in ionic radii makes diffusivity of ions difficult and leads to the formation of stress in lattice [37]. In our system also due to large difference in ionic size and charge between Eu3+(r = 94.7 pm, CN = 6) and Zn2+(r = 60 pm, CN = 4) the doping of Eu3+...
The effective diffusivity coefficient of DO is calculated to be 0.0172m2/d, which means the turbulence diffusion prevailes against the molecular diffusion inside the biocarrier.doi:10.3321/j.issn:0250-3301.2007.03.027ZHOU XiaohongSHI Hanchang
Especially, the effective diffusivity along the direction perpendicular to bedding planes was much lower than that along the direction parallel to bedding planes. In addition, an effective diffusivity model was developed, which could be used to describe the mass transfer of oxygen in the ash layer ...
The oxygen diffusivity of paper type porous media, which is generally used as a GDL, was measured with respect to its liquid water content using experimental apparatus consisting of an oxygen sensor based on the galvanic cell. A numerical method was established to obtain the effective oxygen ...
the effective diffusivity along the direction perpendicular to bedding planes was much lower than that along the direction parallel to bedding planes.In addition,an effective diffusivity model was developed,which could be used to describe the mass transfer of oxygen in the ash layer of oil shale ...
Oxygen diffusion in porous media (ODPM) with rough surfaces (RS) under dry and wet conditions is of great interest. In this work, a novel fractal model for the oxygen effective diffusivity of porous media with RS under dry and wet conditions is proposed. The proposed fractal model is ...
