In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... En savoir plus
In this example, the etching of silicon in a CF4/O2 plasma reactor is studied using a global model. Parametric sweeps for ion energy and oxygen mole fraction are computed. En savoir plus
Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... En savoir plus
In this model, an axial field magnetic gear with a gear ratio of 5:2 is modeled. Both the high-speed and low-speed rotors consist of permanent magnets and back iron. The low-speed rotor consists of five pole pairs, while the high-speed rotor consists of two pole pairs and the stationary ... En savoir plus
This tutorial demonstrates how to modify a concentration-independent (also known as a secondary current distribution) liquid alkaline water electrolyzer with concentrated electrolyte theory to explicitly resolve local electrolyte and solvent concentrations (thereby creating a tertiary ...

This is a conceptual model of a microphone placed in an infinite baffle (flush mounted). The purpose is to determine the free-field level correction curve of the setup, which includes the exterior domain, microphone grid, and volume between the grid and the diaphragm. The microphone ...

In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... En savoir plus
This model demonstrates three different ways to find the eigenfrequencies of a rectangular metallic cavity. The first method uses an eigenfrequency study step together with the Electromagnetic Waves, Beam Envelopes interface. Here, it is important to define a wave vector for the physics ... En savoir plus
This model is a verification case to attest the behavior of turbulence models and wall functions in the boundary layer of a turbulent flow. The velocity and the temperature are compared to the theoretical curves in a wall-resolved and a wall-modeled approach using the Algebraic y+ ... En savoir plus
