Description
We propose to conduct new, additional dynamic CFD simulations of a fluid flow through porous reticulated vitreous carbon electrodes in the electrochemical reactor, which will be supportive and fully complementary with conducted experiments and basic models. The cross-correlation of CFD simulations conducted in COMSOL and laboratory studies will deliver additional knowledge of the observed processes allowing for improved understanding of phenomena and a finer optimization of reactor design.
Process optimization can be pursued by not only a material design but also to a thoughtful design of the
Summary of the results
Porous media are encountered in many natural and man-made systems. The need for advanced porous media modeling spans many industries and application areas such as processes in fuel cells, drying of pulp and paper, food production, filtration processes, and so on. The model of a fluid flowing through a porous structure, obtained by X-ray microtomography, supported by CFD simulation has been built. In the Pre-Design phase has been identified parameters that will be varied, and their effect on the simulation
results (components, structure formation options). Selected optimal criteria (a set of characteristics that should be optimal – minimum or maximum, depending on the specific task).
In the design phase has been identified of two scales of the model (microscopic and macroscopic). Simplification of the 3D model acquired by X-ray microtomography (according to the two scales identified) took longer than expected. A model at two scales was built. In the optimization phase, the problem has been solved (iteratively). Representative volume element (RVE) has been built; The model analysis by physico-mathematical problems numerical simulation was done; Based on the results, a set of effective model characteristicswas synthesised.
