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.
Chemical vapor deposition (CVD) is a process used to grow thin films on substrates. In this CVD example, metal inserts for machining tools are coated with titanium nitride (TiN). The titanium nitride layer improves the wear resistance of the metal inserts by increasing the hardness, ... Per saperne di più
In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined ... Per saperne di più
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 ... Per saperne di più
An aperture is often used in electroplating baths in order to improve the uniformity of the deposited metal layer. This example simulates electroplating of a printed circuit board (PCB) in 3D using a secondary current distribution. The size and aspect ratio of the aperture is optimized ... 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 this model of an ammonia-fed solid oxide fuel cell, the required hydrogen is supplied through endothermic thermal decomposition of ammonia. 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 ... Per saperne di più
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 ... Per saperne di più
This tutorial shows how to use the Optimization interface to perform electrode kinetics parameter estimations based on polarization data. A zero-dimensional electrode polarization model is defined that separates kinetics expressions for the metal dissolution and the oxygen reduction ... Per saperne di più
This model uses the Reacting Flow multiphysics interface to simulate a methane steam reformer. The model accounts for the interactions between the chemical reactions, the transport of species, the fluid flow, and the heat transfer in a porous medium. Per saperne di più
Chemical vapor deposition (CVD) is an important step in the process of manufacturing microchips. One common application is the deposition of silicon on wafers in low pressure reactors to obtain uniform deposition thicknesses. This example models the coupled reaction kinetics, fluid ...
