A centrifugal governor is used to control the speed of rotating machinery. One of the most common applications is in controlling the RPM of an engine by regulating the fuel supply. This model illustrates the functioning of a spring loaded centrifugal governor. The dynamics of the ... En savoir plus
A waveguide filter is designed using shape optimization. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. En savoir plus
The model includes a compilation of benchmark examples included in the text book: Shape Memory Alloys: Modeling and Engineering Applications. D. Lagoudas Ed. Springer 2008. The model shows the thermomechanical properties of a NiTi alloy sample subjected to uniaxial tension-compression ... En savoir plus
This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include ... En savoir plus
This example models the radiation of fan noise from the annular duct of a turbofan aeroengine. When the jet stream exits the duct, a vortex sheet appears along the extension of the duct wall due to the surrounding air moving at a lower speed. The near field on both sides of the vortex ...
