A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... En savoir plus
This example illustrates how to model the transport of different contaminants through a ceramic water filter candle with an activated carbon core. These types of water filters can be found in table top gravity filters, as well as attached to the faucet or as part of a larger reverse ... En savoir plus
Carbon deposition on the surface of solid catalysts is commonly observed in hydrocarbon processing. A known problem is that carbon deposits can impede the activity of catalysts as well as block the flow of gas through a catalyst bed. This example investigates the thermal decomposition ...

This model demonstrates the application of COMSOL Multiphysics to a benchmark case of steady-state subsurface fluid flow and transient solute transport along a vertical cross section in an unconfined aquifer. Because of profound geologic heterogeneity, the model must estimate solute ... En savoir plus
The model simulates atmospheric corrosion of a galvanic couple, comprising of an Al-Co-Ce metallic coating and an aluminum alloy, which is in contact with electrolyte film of 100 micrometer thickness. The corrosion inhibitors are released from the metallic coating and are transported ... En savoir plus
This model uses the Reacting Flow multiphysics interface to simulate a methane steam reformer. The model accounts for the interactions between the chemical reactions, the transport of species, the fluid flow, and the heat transfer in a porous medium. En savoir plus
Freeze-drying, or lyophilization, is a process for drying heat-sensitive substances such as foods, blood plasma, and antibiotics. The wet substance is frozen and then, through sublimation, ice (or some other frozen solvent) is removed in the presence of a high vacuum. This example ... En savoir plus
This model tracks a contaminant that enters an aquifer at a point, such as an injection well or toxic spill, and spreads through the aquifer with time. The model has an analytic solution developed by Wilson and Miller. This analytic solution has been used to test several dedicated fluid ... En savoir plus
This example demonstrates how to model moisture transfer and induced swelling in a paperboard roll subject to varying ambient conditions. The material properties of the paperboard are anisotropic. En savoir plus
This example extends the Fuel Cell Cathode tutorial to also include liquid water transport in the oxygen electrode. Liquid water is produced using a user-defined expression for vapor condensation, depending on the relative humidity level in the gas phase. An experimental capillary ... En savoir plus
