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.
Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... Per saperne di più
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
In this model of an ammonia-fed solid oxide fuel cell, the required hydrogen is supplied through endothermic thermal decomposition of ammonia. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in ... Per saperne di più
This example simulates an oil droplet rising through a suspension. The suspension is initially stratified, with a dense layer between two clear layers. The droplet is initially located in the bottom clear layer. The particles in the suspension start to sediment toward the bottom of the ... Per saperne di più
Acoustic droplet ejection is a non-contact, highly controllable method for liquid handling emerging in applications such as printing, biomedical, semiconductor assembly, and mass spectroscopy. The modeling approach assumes separation of acoustic and flow time scales. First, a focused ... Per saperne di più
In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... Per saperne di più
Recent advances in the fabrication of microfluidic systems require handling of live cells and other micro particles as well as mixing. All this can, for example, be achieved using acoustic radiation forces and the viscous drag from the streaming flow. Streaming: Due to the nonlinear ... Per saperne di più
This model tracks a contaminant that enters an aquifer at a point, such as an injection well or toxic spill, and spreads through the aquifer with time. The model has an analytic solution developed by Wilson and Miller. This analytic solution has been used to test several dedicated fluid ... Per saperne di più
This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field. The model couples the momentum balance to an energy balance through an equation, dependent on temperature, being ... Per saperne di più
In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... Per saperne di più
