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.
In this example, three parallel pipelines of length 68 km and a horizontal separation distance of 10 m between them are protected against corrosion by an impressed current cathodic protection (ICCP) system using a series of anodes. Each anode is connected to all three pipelines, ... Read More
This example considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... Read More
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... Read More
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... Read More
This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to ... Read More
A monopile foundation is a large-diameter structural element that can be used to support structures like offshore wind turbines. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. The model can be used to ... Read More
This example shows how to use the Parameter Estimation and Experiment features in the Reaction Engineering interface for optimization with multiple experimental data input files. The application finds the Arrhenius parameters of a first order reaction where Benzene diazonium chloride ... Read More
Due to its high capacity, silicon (Si) is often added to graphite in the negative electrode of lithium-ion batteries. Silicon–graphite blended electrodes may exhibit significant thermodynamic voltage hysteresis (“path dependence”) because the equilibrium potential of the lithium–silicon ... Read More
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 ... 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
