Theoretical and experimental study of solid oxide fuel cell (SOFC) using impedance spectra
… numerical modeling of SOFCs: the multicomponent gas diffusion in porous electrode at the anode and the heterogeneous electrocatalysis of oxygen reduction reaction (ORR) at the cathode. First, anode was diagnosed to be mainly controlled by multicomponent gas diffusion inside the anode bulk …

Modeling of solid oxide fuel cells
… on a comprehensive approach that include the dusty-gas model (DGM) for gas transport in the porous electrodes, the detailed heterogeneous elementary reaction kinetics for the thermo-chemistry in the anode, and the detailed electrode kinetics for the electrochemistry at the triple-phase …

Diffusion-reaction characteristics of benzene hydrogenation utilizing a supported nickel catalyst
… compared to theoretical ones generated using the dusty gas model. Minimizing the residual sum of squares between the two yielded relationships for the effective diffusivity and the catalyst tortuosity, both of which reproduced values reported in the literature. These relationships were based on …

Kinetics of Heat and Mass Transfer Near the Liquid-Vapor Interface
… Monte Carlo calculations to validate the dusty-gas model. We demonstrate that this model accurately and efficiently predicts gas transport in our experimental system and state-of-the-art membranes that could be used for high-selectivity membrane separation processes. Finally, we carefully …

Use of Volumetric Heating to Improve Heat Transfer During Vial Freeze-Drying
… mass transport equations derived from the dusty gas model was also presented. This model offers the benefit of a more accurate prediction of mass transport through the porous dried layer. NOTE: (09/2008) An updated copy of this ETD was added after there were patron reports of problems with …

Multiphysics algorithms for the simulation of geological materials under extreme conditions: the evolution and transport of ablated material
… the vaporised material being removed by a purge gas. As an immature technology, it presents new challenges that are difficult to study experimentally due to the extreme conditions. This study is concerned with the design and implementation of a numerical model capable of simulating dust-laden …
