The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This example treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow. The equations that are solved are the ... Read More
Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting ... Read More
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 ... Read More
In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are ... Read More
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. Read More
High-performance liquid chromatography (HPLC) is a common method of separating, identifying, and quantifying each chemical compound in a mixture. HPLC is found in the pharmaceutical, biotech, and food industries. The Liquid Chromatography app simulates the separation of two species ... Read More
The copper current collector on negative graphite electrodes in lithium-ion batteries have been seen to dissolve at over discharge. This can be a safety concern as the dissolution damages the current collector irreversibly and dissolved copper ions can redeposit and form dendrites. ... Read More
This is a demonstration of how to use the thermodynamics functionality in the COMSOL Multiphysics® software to make flash calculations. A flash calculation is an equilibrium calculation of a system where several species and phases are present at the same time. The system in ... Read More
In a redox flow battery electrochemical energy is stored as redox couples in the electrolyte, which is stored in tanks outside the electrochemical cell. During operation, electrolyte is pumped through the cell and, due to the electrochemical reactions, the individual concentrations of ... Read More
Battery electrodes featuring large heterogeneities in terms of particle sizes may sometimes not be adequately described by homogenized models using one single particle size only. As an alternative to adding multiple instances of the Additional Porous Electrode material node, this ... Read More
