Nonisothermal Plug-Flow Reactor
This example considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... En savoir plus
Electrochemical Impedance Spectroscopy in a Fuel Cell
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... En savoir plus
Balanced Patch Antenna for 6 GHz
Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... En savoir plus
1D Lithium-Ion Battery Drive-Cycle Monitoring

Large Eddy Simulation of a 3D Hill Geometry
The present example simulates the turbulent flow over a 3D hill geometry using the Large Eddy Simulation (LES) interface with synthetic turbulence at the inlet boundary. En savoir plus
Slot-Die Coating with Channel Defect
This is a tutorial of a slot die coating process in 3D where the channel is obstructed. The example uses a two-phase flow phase-field method with a non-Newtonian power-law fluid. The effects on the film thickness of the channel obstruction can clearly be seen. En savoir plus
Greenhouse Effect
This model illustrates the greenhouse effect in a box covered by a plate and exposed to sun radiation over a day. The temperature variation is monitored in two cases: with a plate made of glass, transparent in the solar spectral band and opaque for the ambient solar band with a fully ... En savoir plus
Disc Resonator Anchor Losses
This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially ...
