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.
Liquid-liquid extraction is a process used to separate or transfer species between two immiscible liquids. Transfer of species from one phase to the other is driven by a difference in relative solubility. In this model a water filled extraction column is studied. Oil droplets containing ...

This application presents an example of pressure driven flow and electrophoresis in a 3D micro channel system. Researchers often use a device similar to the one in this model as an electrokinetic sample injector in biochips to obtain well-defined sample volumes of dissociated acids and ... Per saperne di più
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 ... Per saperne di più
This example shows how to make a simple model for a binary distillation process. A thermodynamics property package, available in the Chemical Reaction Engineering Module, is created to study the separation of a nonideal mixture of ethanol and water. The required equilibrium relationship ... Per saperne di più
Recovery of precious metals in recycling of electronics, or extraction from ore, is usually performed through leaching of the metal into an aqueous phase. Precious metals require the use of an oxidant, and often, a complexant. In the case of gold, the cyanide anion (CN-) forms a soluble ... Per saperne di più
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 ... 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
Crystallization is an important separation process in the chemical industry. It is used for the production of pharmaceuticals and industrial chemicals. It can also be used in resource recovery as a way of separating valuable materials from waste. This model solves a discretized ... Per saperne di più
Kinetic analysis of catalytic reactions is essential for understanding rate behavior as well as the reaction mechanism. Developing knowledge of intrinsic reaction kinetics and of rate equations is central to reaction engineering studies aimed at improving reactor design. This model ... 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.
