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.
This example uses the Granular Flow interface to model the formation of the grain heap and then its subsequent spreading using a cylindrical roller. The roller has a combined rotational and translational motion. The resulting powder bed is then analyzed to determine its quality based on ... Per saperne di più
Turbulent flow, Elliptic Blending R-ε interface is used to analyze fully developed turbulent flow in a spanwise rotating channel. Due to the influence of Coriolis force on turbulence, profiles of the flow variables are skewed at moderate rotation rate. The asymmetry between cyclonic ... Per saperne di più
At the bottom of an oil well, the pressure and temperature can differ significantly from those at the surface. As the oil mixture flows upward and the pressure decreases, phase changes may occur. At the wellbore inlet, the mixture may already contain both liquid and gas phases. ... Per saperne di più
This model demonstrates the filtration of grains of three different sizes as they pass through two vibrating sieves of different hole sizes. Per saperne di più
This model showcases a nail penetration experiment into a layered battery. It couples the Solid Mechanics, Lithium-Ion Battery, and Heat Transfer interfaces. A nail is punched into a sandwiched battery consisting of two electrodes and a separator. As soon as the nail connects both ... Per saperne di più
This model shows three methods to focalise external irradiation with a convex glass lens made of either: Semitransparent Surface with no reflection. Refractive Interface following the Fresnel's relations. Dielectric Window absorbing ultraviolet and infrared radiations. Per saperne di più
Coaxial pipes are used in a variety of applications, including geothermal borehole heat exchangers. In this model, cold water is injected through the inner pipe and returns through the annular region between the inner and outer pipes, absorbing heat from the surrounding subsurface. The ...

As an analyte band flows through a curved channel in an electroosmotically driven flow, dispersion of the band occurs due to gradients in the fluid velocity across the channel. These velocity gradients result from differences in the electric field acting at the walls within the curved ... Per saperne di più
In electrosurgery, high-power AC current from a probe is driven into tissue in order to cut and coagulate it. The current causes rapid Joule heating near the tip, and as temperatures reach 100°C, water and blood vaporize and the tissue desiccates, enabling cutting or sealing. This ... Per saperne di più
Free-surface calculations in the predefined flow interfaces are currently limited to time-dependent studies when using the built-in boundary conditions. Here, a stationary formulation following Romero et al. [1] is implemented using equation contributions. The attached slides describe ... Per saperne di più
