This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... En savoir plus
Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... En savoir plus
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... En savoir plus
This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include ... En savoir plus
This model presents a 2D simulation of transient arc discharge movement along guided copper rails. While accurately modeling transient arcs typically requires a 3D simulation, the 2D approach offers greater efficiency and remains valuable for initial investigations and demonstration ...

This model demonstrates how to model phenomena defined in different dimensions in a fully coupled manner using COMSOL Multiphysics. Whereas in most cases the reaction rate expression is defined as a function of the concentrations of the reactants and products, in adsorption reactions ... En savoir plus
The Free Molecular Flow interface, available in the Molecular Flow Module, is an efficient tool for modeling extremely rarefied gases when the gas molecules move much faster than any geometric entities in the domain. For turbomolecular pumps, in which the blades move at speeds comparable ... En savoir plus
A surface acoustic wave (SAW) is an acoustic wave propagating along the surface of a solid material. Its amplitude decays rapidly, often exponentially, through the depth of the material. SAWs are utilized in many kinds of electronic components, including filters, oscillators, and ... En savoir plus
This tutorial uses a “black-box” approach to define a battery model based on a small set of lumped parameters, assuming no knowledge of the internal structure or design of the battery electrodes, or choice of materials. The input to the model is the battery capacity, the initial state ... En savoir plus
