The fluid flow in seals causes a strong restoring radial force, opposing the shaft motion. Also, there is a cross coupled force due to the axial variation of the circumferential flow. The first type of force always has a stabilizing effect on the rotor, whereas the second one in certain ... En savoir plus
In this example, a tensile test is simulated at four different strain rates. The Johnson–Cook hardening law is used to model the strain rate dependency of the plastic hardening. The temperature distribution and thermal expansion caused by the heating generated by the plastic ... En savoir plus
This model demonstrates the use of moving meshes in the application of copper electrodeposition on circuit boards. In these environments, the presence of cavities or 'trenches' are apparent. The model makes use of the Tertiary, Nernst-Planck interface for electrodeposition to keep track ... En savoir plus
This model exemplifies the basic principles of crevice corrosion and how a time-dependent study can be used to simulate the electrode deformation. The model is in 2D and the polarization data for the corrosion reaction is taken from a paper by Absulsalam and others. The model and the ... En savoir plus
The graviational three body problem involves the calculation of the positions and velocities of three objects under mutual gravitational attraction, given their position and velocity at some initial time. While the three-body problem does not have a general analytic solution and is ... En savoir plus
Capacitively coupled RF discharges can operate in two distinct regimes depending on the discharge power. In the low power regime, known as the alpha regime, the electric field oscillation is responsible to heat and create electrons. In the high power regime, known as gamma regime, the ... En savoir plus
This model computes the lightning-induced voltage on an overhead line positioned above a lossy ground. It includes parameters like the inclination angle of lightning channels and soil conductivity, enabling straightforward analysis of their impacts. The calculated induced voltage aligns ...
