This model presents a 2D axisymmetric dipolar microwave plasma source sustained through resonant heating of the electrons. This is known as electron cyclotron resonance (ECR), which occurs when a suitable high magnetic flux density is present along with the microwaves. This is an ... En savoir plus
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... En savoir plus

An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... En savoir plus
This suite of examples illustrate the modeling of selective NO reduction, that occurs as flue gases pass through the channels of a monolithic reactor in the exhaust system of a motored vehicle. The simulations are aimed at finding the optimal dosing of NH3, the reactant that serves as ... En savoir plus
This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... En savoir plus
The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by seawater, sound navigation ranging, or sonar, is one of the main methods used for the detection of submarines. Sonar systems are also used for underwater ...

Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the ...

This is a model of the secondary current distribution in a zinc electrowinning cell. The model investigates the impact on the current distribution when changing the electrode alignment in a parametric study. The geometry is in 2D. En savoir plus
In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... En savoir plus
