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 treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow. The equations that are solved are the ... Per saperne di più
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... Per saperne di più
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. 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
Modeling packed beds, monolithic reactors, and other catalytic heterogeneous reactors is substantially simplified with the Reacting Flow in Porous Media multiphysics interface. This defines the diffusion, convection, migration, and reaction of chemical species for porous media flow ... Per saperne di più
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... 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
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
This non-conventional model of porous media flow utilizes creeping (Stokes) flow in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. ... Per saperne di più
This is a tutorial model of the coupling between flow of a fluid in an open channel and a porous block attached to one of the channel walls. The flow is described by the Navier-Stokes equation in the free region and a Forchheimer-corrected version of the Brinkman equations in the porous ... Per saperne di più
