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.
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 ... Read More
Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with ... Read More
Lithium-ion batteries can have multiple active materials in both the positive and negative electrodes. For example, the positive electrode can have a mix of active materials. These materials can have different design properties (volume fraction, particle size), thermodynamic properties ... Read More
This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. Read More
This model presents a study of the current density distribution in a solid oxide fuel cell (SOFC). The model includes the full coupling between the mass balances at the anode and cathode, the momentum balances in the gas channels, the gas flow in the porous electrodes, the balance of ... Read More
The zinc bromine redox flow battery is an electrochemical energy storage technology suitable for stationary applications. Compared to other flow battery chemistries, the Zn-Br cell potentially features lower cost, higher energy densities and better energy efficiencies. In the cell ... Read More
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 ... Read More
In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first benchmark case from the InterFrost project, which was initiated to compare ... Read More
Impedance tubes are used for estimating the surface impedance of various samples, for example, a layer of porous material used for sound insulation. This model shows how the five material parameters of the Johnson-Champoux-Allard model can be estimated from the pressure at two ... 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
