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 model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature. A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a ... Per saperne di più
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... Per saperne di più
This example demonstrate two-phase flow in a porous medium which contains a low permeable lens. The heavier phase infiltrates the porous medium, so the low permeable lens is infiltrated only when a critical saturation at the outside is reached. Per saperne di più
Droplet evaporation is ubiquitous in everyday life, and is essential in many industrial processes such as ink-jet printing, cleaning or coating of surfaces, and phase change heat transfer. In this model, a water droplet placed on a solid substrate evaporates in air. We solve the ... Per saperne di più
We present the results from a comparison of the level set, phase field, and moving mesh methods for modeling free liquid surfaces in the COMSOL Multiphysics® software. The comparison is carried out using an example problem. The example studies the formation of surface waves ... Per saperne di più
The catenary is the geometrical shape that corresponds to the curve followed by an idealized chain or cable supported at both ends and hanging under its own weight. The viscous catenary problem describes the motion of a cylinder of highly viscous fluid, supported at its ends as it flows ... Per saperne di più
The Particle Tracing for Fluid Flow interface is used to compute the erosion of a pipe bend. The amount of material lost is computed using different erosion models. Per saperne di più
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... Per saperne di più
Swirl flow is an application that involves steady rotational flow around an axis. Rather than modeling this process in 3D, COMSOL Multiphysics provides a 2D axisymmetric interface where the flow in the rotational direction is still included in the equations. This example shows the ... Per saperne di più
In the semiconductor manufacturing process, photoresist coating is an important process and the thickness of the photoresist layer needs to be precisely controlled. Usually, the photoresist layer is thinned by spin coating. The specific principle is to use centrifugal force to throw ... Per saperne di più
