This example replicates the results of the Jelly Roll tutorial example using a flattened representation of the wound spiral-based geometry. See that model entry for details on the background, original geometry, materials, and the general physics setup. Mapping the original problem to a ... Mehr lesen
Electrochemical glucose sensors use amperometric methods to measure the concentration of glucose in a sample. This example models the diffusion of glucose and ferri/ferrocyanide redox mediators in a unit cell of electrolyte above an interdigitated electrode. The sensor gives a linear ... Mehr lesen
This example models co-electrolysis of H2O and CO2 using a solid oxide electrolyzer cell. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in the H2 and O2 gas flow channels, the energy balance ...

Electrodialysis is a separation process for electrolytes based on the use of electric fields and ion selective membranes. Some common applications of the electrodialysis process are: Desalination of process streams, effluents, and drinking water pH regulation in order to remove acids ... Mehr lesen
The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the ... Mehr lesen
This application shows how mass transfer out from a thin 3D domain can be approximated using a 2D component with the domain feature Out-of-Plane Flux. This feature is useful when the concentration gradient in the out-of-plane direction (along the thickness) is small, and decreasing the ... Mehr lesen
This model demonstrates the "butterfly" filling mechanism for copper electrodeposition in a Through-Hole (TH) via exposed to an electrolyte containing halide-suppressor additives. The Tertiary Current Distribution, Nernst Planck interface in combination with Deformed Geometry is used ... Mehr lesen
Tubular reactors are often used in continuous large-scale production, for example in the petroleum industry. One key design parameter is the conversion, or the amount of reactant that reacts to form the desired product. In order to achieve high conversion, process engineers optimize the ... Mehr lesen
This example models galvanic corrosion between two different phases in a magnesium alloy for a representative cross-sectional microstructure configuration. The Phase Field interface is used here to model dissolution of a constituent phase leading to topological changes. The electrode ... Mehr lesen
Oxide jacking is the process by which reinforced concrete cracks, due to the corrosion of the reinforcing rebar rods. The corrosion process causes growth of an oxide layer on the rebar, which in turn causes internal stresses in the concrete. If the corrosion process is allowed to ... Mehr lesen
