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.
The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important practical features relevant to automobile bodies. This model describes how to calculate the turbulent flow ... Per saperne di più
This example shows how the mixing capability of a stirred vessel can be evaluated. To efficiently reach the steady operational conditions the turbulent flow is solved for using a frozen rotor analysis, and a following time dependent simulation. When a quasi-steady flow field has ... 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
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
This example considers the natural convection of air above a smoldering incense stick. This kind of flow often shows a transition from laminar to turbulent which is nicely visualized by the smoke produced by the slow burning of the incense. The model uses the Nonisothermal Flow, LES RBVM ... Per saperne di più
High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 ... Per saperne di più
Silicon carbide (SiC) epitaxial furnaces are a specialized equipment for the production and preparation of SiC epitaxial wafers. This example model demonstrates the process of preparing an SiC epitaxial wafer based on the physical vapor transport (PVT) method in a furnace. This involves ... Per saperne di più
This example demonstrates how to set up the classical external-flow problem of solving for the high-speed, compressible, turbulent flow over the ONERA-M6 wing. The problem involves finding a steady-state solution of the flow field around the 3D, swept wing geometry, immersed in a ... Per saperne di più
This example shows the modeling of a resin transfer molding (RTM) process for a wind turbine blade using the Two-Phase Flow, Level Set, Brinkman Equations interface. Resin is injected into a preform consisting of different composites with different anisotropic permeabilities. Per saperne di più
Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2-f turbulence model is used to simulate the flow in a ...
