The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric. This model simulates partial discharges in a spherical ...

This model simulates the electrohydrodynamic (EHD) flow of a dielectric liquid around a wire electrode positioned between two parallel flat-plate electrodes. The ion transport is described using the Poisson–Nernst–Planck equations, while fluid motion is governed by the Navier–Stokes ... En savoir plus
This model demonstrates an efficient approach to simulating a thin, spherical, large radome using a 2D axisymmetric formulation with cubic discretization. The axisymmetric method captures full 3D behavior for azimuthally symmetric geometries at only a fraction of the computational cost. ... En savoir plus
This tutorial model explores the behavior of a microwave plasma torch. The plasma is generated within a dielectric tube inserted in a rectangular waveguide.

This model demonstrates dielectric barrier discharge (DBD) in air subjected to an AC applied voltage. As the voltage amplitude increases, the discharge intensity correspondingly strengthens. Furthermore, the dominant component of the discharge current transitions from displacement ... En savoir plus
Tutorial example of the RF heating of passive conductive implants (rod and screws) inserted in three vertebrae during MRI. The RF fields are locally enhanced in the proximity of a passive conductive implant resulting in the heating of the portion of tissue facing the implant's surface. En savoir plus
This model calculates the DC breakdown voltage between parallel electrodes in air using a detailed charge transport approach. It is currently one-dimensional for simplicity but can be extended to other gases and dimensions. The results closely match experimental data found in the ... En savoir plus
Manual design optimization typically requires numerous sweeps over a parameterized geometry, but it does not guarantee optimal performance under given conditions. Shape optimization removes the need for explicit parameterization and can achieve comparable or even better performance in a ... En savoir plus
The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... En savoir plus
