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 considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... Per saperne di più
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... Per saperne di più
This model demonstrates an integrated structural-thermal-optical performance (STOP) analysis of an optical system. The Petzval Lens tutoral is used as the basis for this model, together with a simple barrel geometry The isothermal model performs a Parametric Sweep over several uniform ... Per saperne di più
This model is a benchmark model for the Slip Flow interface. It is based on both analytic and numeric calculations. Air at atmospheric pressure flows through a conducting micro-channel connecting two reservoirs maintained at different temperatures. A flow between the two reservoirs ... 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
During quenching of steel, austenite decomposes into phases such as ferrite, pearlite, bainite, and martensite. A common way to illustrate the phase transformation characteristics of a particular steel alloy is to use transformation diagrams. Two of the most commonly used diagram types ... Per saperne di più
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... Per saperne di più
This model describes the evaporation of a droplet that consists of concentrated solution of acetone and water. It accounts for the coupled phenomena of chemical species transport and heat transfer over phase boundaries (liquid-gas boundary) as well as for multiphase flow. The droplet ... Per saperne di più
This tutorial model solves for an inductively coupled plasma reactor in a mixture of argon/oxygen. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. 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
