This tutorial analyzes the resistive heating (Joule heating) of a busbar assembly designed to conduct a direct current from a current source to the anode in an electrolysis process. En savoir plus
Voltammetry is modeled at a microelectrode of 10um radius. In this common analytical electrochemistry technique, the potential at a working electrode is swept up and down and the current is recorded. The current-voltage waveform ("voltammogram") gives information about the reactivity and ... En savoir plus
The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the ... En savoir plus
This model illustrates the use of COMSOL Multiphysics for modeling of ionic current distribution problems in electrolytes, in this case in human tissue. The problem is exemplified on a pacemaker electrode, but it can be applied in electrochemical cells like fuel cells, batteries, ... En savoir plus
This model shows how to model a simple Shockley diode— a four-layer PNPN semiconductor device. The Shockley diode is also named as thyristor. In this model, the Analytic Doping Model node is utilized to define the doping profiles for each domain. A time-dependent study is employed to ... En savoir plus
This tutorial model solves for an inductively coupled plasma reactor with RF bias (also known as ICP/CCP reactors) in a mixture of argon/chlorine. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. En savoir plus
This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... En savoir plus
This is a model of a MEMS microphone solved in the frequency domain including the DC prestress effects. The model is set up using the Electromechanics multiphysics interface, Thermoviscous Acoustics, and Pressure Acoustics. The microphone consists of a perforated plate and a prestressed ...

This tutorial model is kindly provided by Riccardo Vietri, James Ransley and Andrew Spann at Veryst Engineering, LLC. Piezoelectric micropumps are frequently used in medical applications because of their ability to precisely control the metering of very small volumes of fluids or gases. ... En savoir plus
This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... En savoir plus
