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 determines the reflection coefficient of plane acoustic waves, at different frequencies and at different angles of incidence, off a water-sediment interface. The ability of the Poroelasitc Waves interface to model the coupled acoustic and elastic wave in any porous substance ... Per saperne di più
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Per saperne di più
This example focuses on the species transport within the gas diffusion layers (GDLs) of a proton exchange membrane (PEM) fuel cell. The geometry models a cell with two adjacent flow channels of different pressures, a situation that may occur in a cell with serpentine flow channels, or in ... Per saperne di più
This model uses the Reacting Flow multiphysics interface to simulate a methane steam reformer. The model accounts for the interactions between the chemical reactions, the transport of species, the fluid flow, and the heat transfer in a porous medium. Per saperne di più
This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. The array is embedded into a layered subsurface model with groundwater flow in one of the ... Per saperne di più
Vacuum drying is a chemical process frequently used in the pharmaceutical and food industries to remove water or an organic solvent from a wet powder. When designing a vacuum drying system, engineers aim to minimize the drying time while maintaining high quality in the product. This ... Per saperne di più
This is one of the two models from the blog post about heat transfer in the subsurface: Coupling Heat Transfer with Subsurface Porous Media Flow Note: Poroelasticity is not included here. Per saperne di più
This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of observations is smaller than the number of unknown parameters, ... Per saperne di più
Modeling flow through realistic porous structures is difficult due to the complexity of the structure itself. Often, resolving the flow field in detail is not feasible; therefore, a macroscopic description of the pore scale structure, which utilize averaged quantities such as porosity ... Per saperne di più
Several factors influence a diesel particulate filter’s (DPF) efficiency and durability. Important issues include the removal of soot particles from the filter membranes and the influence of thermal stress on the ceramic structure, stress that arises during repeated operating cycles. ...
