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.
A journal bearing is composed of an outer cylinder (bearing) wrapped around an inner rotating journal (shaft), with a lubricant separating the two. Under certain operating conditions, cavitation can occur between the bearing and the journal, leading to component damage and failure. ... Per saperne di più
Journal bearings are used to carry radial loads, for example, to support a rotating shaft. A simple journal bearing consists of two rigid cylinders. The outer cylinder (bearing) wraps the inner rotating journal (shaft). The new thin-film flow user interfaces of the CFD Module enables ... Per saperne di più
This example illustrates a linear buckling analysis conducted for a corrugated conical shell, utilizing a single sector of the geometry along with cyclic symmetry periodicity edge conditions. The results are compared to those using the full shell geometry. Per saperne di più
This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... Per saperne di più
Global equations are a way of adding an additional equation to a model. A global equation can be used to describe a load, constraint, material property, or anything else in the model that has a uniquely definable solution. In this example, a structural mechanics model of a spring is ... Per saperne di più
This model analyzes the frequency response of a fuel tank partially filled with fluid. The tank is submitted to a vertical acceleration. Two modeling methods are considered to represent the fluid: a traditional method of smearing the mass of the fluid through the wetted surface of the ... Per saperne di più
This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit ... Per saperne di più
A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical ... Per saperne di più
Electrodialysis is a separation process for electrolytes based on the use of electric fields and ion selective membranes. Some common applications of the electrodialysis process are: Desalination of process streams, effluents, and drinking water pH regulation in order to remove acids ... Per saperne di più
A paraboloidal dish can concentrate solar energy onto a target (receiver), resulting in very high local heat fluxes. This can be used to generate steam, which can be used to power a generator, or hydrogen, which can be used directly as a fuel source. In this model, the heat flux arriving ... Per saperne di più
