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.
The Monte Carlo simulation of flow in a turbomolecular pump can be greatly simplified if the mean radius of the blades is much greater than the spacing between them. Under these conditions, the rotating blades of the pump can be approximated as an infinite row of blades having only ... Per saperne di più
The Boltzmann equation can be solved to validate sets of electron impact collision cross sections. In fact, sets of collision cross sections are traditionally inferred by solving a two-term approximation to the Boltzmann equation and comparing the results to swarm experiments. This model ...

The purpose of this model is to visualize the electric potential in an electrochemical cell, for example a battery. This is done at OCV and during operation. In a battery, this would correspond to OCV, discharge, and recharge. The potential profile is explained both for cells with planar ... Per saperne di più
This tutorial example illustrates the versatility of the Reaction Engineering interface. The hydrogen iodine reaction is modeled in a batch reactor with constant volume. Both isothermal and non-isothermal conditions are modeled. Per saperne di più
The Superlattice Band Gap Tool model helps the design of periodic structures made of two alternating semiconductor materials (superlattices). The model uses the effective mass Schrödinger equation to estimate the electron and hole ground state energy levels in a given superlattice ... Per saperne di più
Whenever dimensions in waveguides become small compared to the viscous and thermal boundary layers it is necessary to model acoustics using thermoacoustics. In the present model the thermoacoustic wave field in a shallow uniform waveguide is modeled and compared to an analytical solution. 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
Some conventional three-port power dividers are resistive power dividers and T-junction power dividers. Such dividers are either lossy or not matched to the system reference impedance at all ports. In addition, isolation between two coupled ports is not guaranteed. The Wilkinson power ... Per saperne di più
This model demonstrates how to simulate surface plasmon polaritons in a thin metal layer embedded in dielectric layers. It calculates the dispersion and propagation length of surface plasmon polaritons as a function of photon energy. Per saperne di più
This example consists of a 2D analysis of propagation modes in the chamber of a muffler. In this case, the muffler walls are considered to be made of a linear elastic material and account for their influence on the modes propagating through the cross section of the chamber. This analysis ... Per saperne di più
