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 illustrates how to set up and solve a tank-in-series model in 0D using the Reaction Engineering interface. The model treats a series of three consecutive tank reactors. A feedback loop continuously adjusts the inlet concentration of the first tank to keep the concentration ... Per saperne di più
A catalyst particle with a hypothetical microstructure is described in detail. The heterogeneous description is approximated in a second model with a homogeneous particle and the results from the two approaches are compared. See: https://www.comsol.se/blogs/modeling-approaches-in ... Per saperne di più
This full-scale, time-dependent model of an offshore oil platform jacket involves modeling coating breakdown and estimating sacrificial anode life and the buildup of calcareous deposits on steel surfaces. The tutorial model aims to answer some of the common questions surrounding ... Per saperne di più
Example of membrane dialysis with a two-layered membrane. A second Reaction Engineering component models a tank connected to the inlet and outlets of the dialysate channel. Per saperne di più
The present model demonstrates diffusion-controlled electrodeposition of copper on microstructured band electrode arrays (MEA). Mass transport by Fickian diffusion of copper ions is solved using the Transport of Diluted Species interface. Dendrite formation as a consequence of diffusion ... Per saperne di più
This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator. Per saperne di più
This tutorial shows how to model transport of the individual ions in a salt melt comprising two binary salts, where the transport equations are defined using concentrated solution theory. The example model defines a molten carbonate fuel cell (or electrolyzer), with a 1D-model geometry ... Per saperne di più
Oscillating chemical reactions were long thought to simply not exist in homogeneous solution, and even the poster child, the Belousov–Zhabotinsky reaction, met such an initial skepticism, that even though it was discovered in 1951, it took almost 20 years for it to gain widespread fame. ...

This tutorial demonstrates how to modify a concentration-independent (also known as a secondary current distribution) liquid alkaline water electrolyzer with concentrated electrolyte theory to explicitly resolve local electrolyte and solvent concentrations (thereby creating a tertiary ...

This example models a small reverse osmosis water desalination unit. The unit consists of a spirally wound semi-permeable membrane through which the water is forced under high pressure. The membrane retains the salt, such that on the permeate side fresh water is produced and on the ... Per saperne di più
