WebbTwo methods are proposed to calculate these parameters as functions of the Péclet and the Péclet-Dahmköhler numbers. In the first method called the pore-scale model (PSM), the porous medium is discretized by the level set method; the Stokes and convection-diffusion equations with reaction at the wall are solved by a finite-difference scheme. Webbför 2 dagar sedan · The Journal of Porous Materials is an international, interdisciplinary periodical focused on the rapid publication of high quality, peer-reviewed papers on synthesis, processing, characterization and evaluation of all porous materials. The journal addresses the dramatic pace of progress in the design and synthesis, characterization …
Webb25 feb. 2024 · The improved performance in porous architecture is linked to the enhanced active specific surface and direct channels leading to improved electrolyte interaction with the redox-active sites. A theoretical model utilizing Fick's law is proposed, that can consistently explain the experimental data. WebbPorous high-entropy ceramics with 81.5% porosity demonstrated excellent thermal properties, showing a thermal conductivity of 0.0642 W/ (m·K) at room temperature and 0.1467 W/ (m·K) at 1200 °C. The unique pore structure with a micron size contributed to its excellent thermal insulating performance.
