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.
Heat pipes are designed to transfer heat efficiently through vaporization, mass transfer, and condensation of a working fluid. They are found in a wide variety of applications where thermal control is of importance, with cooling of electronics being a prominent example. Inside a heat ... Per saperne di più
This model illustrates the effect of oxygen and hydrogen formation and recombination on the performance and self-discharge of an electrochemical capacitor with a water-based electrolyte. A load cycle consisting of mixed constant current pulses and rest periods at an open circuit is ... Per saperne di più
This model illustrates the use of COMSOL Multiphysics for modeling of ionic current distribution problems in electrolytes, in this case in human tissue. The problem is exemplified on a pacemaker electrode, but it can be applied in electrochemical cells like fuel cells, batteries, ... Per saperne di più
A Branch Line Coupler (Quadrature 90° Hybrid) is a four-port network device with a 90° phase difference between two coupled ports. The device can be used for a single antenna Transmitter/Receiver system or an I/Q signal splitter/combiner. The objective of this model is to compute the S ... Per saperne di più
The Poroelasticity interface couples Darcy's law and solid mechanics to assess deformation of porous media that results from fluid withdrawals. The model builds on top of the Terzaghi Compaction example. Results from Terzaghi compaction and Biot poroelasticity analyses are compared to ... 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 tutorial model shows how a plate-fin heat exchanger made of aluminum is used to cool down hot oil with colder air. In order to maximize heat transfer, the heat exchanger is made of a porous aluminum matrix in which the hot oil flows. Heat is conducted through aluminum fins in ... Per saperne di più
This example reproduces parts of the study of Ref. 1 on the thermal contact resistance at the interface between a heat sink and an electronic package. Eight cooling fins equip the cylindrical heat sink and contact is made at the radial boundaries of the package. The efficiency of the ... Per saperne di più
During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... Per saperne di più
