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 computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.7 (heavily oxidized). A more ... Per saperne di più
Solar concentrator/cavity receiver systems can be used to focus incident solar radiation into a small region, generating intense heat which can then be converted to electrical or chemical energy. A common figure of merit in solar thermal power systems is the concentration ratio, or the ... Per saperne di più
This app demonstrates the following: Geometry parts and parameterized geometry A results table form object containing outputs Finned pipes are used for coolers, heaters, or heat exchangers to increase heat transfer. They come in different sizes and designs depending on the ... Per saperne di più
The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted to a laser pulse on one of its faces. In turn, the opposite face is heated up by around 1 K. As the pulse is uniform and ... Per saperne di più
Basin-type insulators are critical components in Gas-Insulated Metal-Enclosed Switchgear (GIS). During the manufacturing process, the curing of epoxy resin can generate residual stresses that may lead to the formation of cracks. Over time, these cracks can cause partial discharges, ...

Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface. This example illustrates the modeling of such a CVD reactor where triethyl-gallium first decomposes, and the reaction products ... Per saperne di più
This is a model of a simple thermoacoustic engine that includes a thermal stack to convert thermal energy to acoustic energy. The model is set up using two approaches: 1) Using a linear perturbation (acoustic) approaches solving the fluid motion with the Thermoviscous Acoustics, ... Per saperne di più
This example exemplifies how to model thermal phase change that is subject to hysteresis. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "Thermal Modeling of Phase-Change Materials with Hysteresis" as well as: "How to Use State ...

This model utilizes the thermoviscous acoustic interface in a sub-model to obtain detailed results for the transfer impedance of a perforated plate (including the thermal and viscous losses). The impedance is in turn used as an internal impedance in a pressure acoustic model of a ... Per saperne di più
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Per saperne di più
