La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
This example models cathodic protection of a steel reinforcing bar in concrete. Three different electrochemical reactions are considered on the steel surface. Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend ... Per saperne di più
This application demonstrates how you can access and include external thermodynamic and physical property calculations in your simulation, using the Thermodynamics feature. The example shows how you can easily modify the predefined Plug-flow reactor type in the Reaction Engineering ... Per saperne di più
This model describes the evaporation of a droplet that consists of concentrated solution of acetone and water. It accounts for the coupled phenomena of chemical species transport and heat transfer over phase boundaries (liquid-gas boundary) as well as for multiphase flow. The droplet ... Per saperne di più
Magnesium alloys are attractive alternatives as lightweight materials in various fields of engineering. Magnesium is however relatively non-noble and may suffer considerable galvanic corrosion when being used in conjunction with other metals, for instance when mounting an Mg alloy ...

Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is ... Per saperne di più
This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The ... Per saperne di più
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 ... Per saperne di più
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ...

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 ... Per saperne di più
This example introduces three different models for a lateral flow assay for the detection of coronavirus antibodies. These models are as follows: 3D model for studying possible symmetries in the spreading of the liquid sample in the test strip. The 3D model shows that the flow is ... Per saperne di più
