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.
Real reactors can be modeled as combinations of ideal reactors. In this example the so-called "Dead zone model" is utilized. Two ideal CSTRs with interchange are set up to model the real reactor. One CSTR represents the highly agitated region and the other the less agitated region. For ... Per saperne di più
This app demonstrates the following: How an app can be used as a teaching tool An 8 question multiple choice quiz where the answers can be sent to the grader by email This app calculates the equilibrium compositions in gas phase conversion of ethylene to ethanol. It allows you to ... Per saperne di più
This model file was used for creating the plots featured in the blog post "How to Model Ion-Exchange Membranes and Donnan Potentials". Per saperne di più
As reactant monomer converts into polymer chains, the density of the reacting mixture often changes notably. In this example you will look at how this effect impacts the total production of polymer in a process. The liquid phase polymerization takes place in a semibatch reactor, where ... Per saperne di più
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. Per saperne di più
This example studies the kinetics of the neutralization of chlorine gas in water solution. The model assumes that the fluid volume is perfectly mixed and constant. This means that the chlorine has dissolved to an almost saturated state (1·10-2 mol/m3) and that the hydroxide has also ... 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.

This example extends the analysis made in the model Electrodeposition on a Resistive Patterned Wafer by including the diffusion and convection of copper ions in the electrolyte. The coupled mass transport convection-diffusion effects are of interest in this type of reactor since they ... Per saperne di più
This example extends the corrosion protection system analysis of the single oil platform example by modeling the influence of multiple oil platforms placed in an array. The use of the Current Distribution on Edges, BEM interface significantly reduces the problem size and computational ... Per saperne di più
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Per saperne di più
