A monopile foundation is a large-diameter structural element that can be used to support structures like offshore wind turbines. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. The model can be used to ... En savoir plus
This example shows how to make a simple model for a binary distillation process. A thermodynamics property package, available in the Chemical Reaction Engineering Module, is created to study the separation of a nonideal mixture of ethanol and water. The required equilibrium relationship ... En savoir plus
The zinc bromine redox flow battery is an electrochemical energy storage technology suitable for stationary applications. Compared to other flow battery chemistries, the Zn-Br cell potentially features lower cost, higher energy densities and better energy efficiencies. In the cell ... En savoir plus
Lead-acid batteries are widely used as starting batteries for various traction applications such as cars and trucks and so forth. The reason for this is the fairly low cost in combination with the performance robustness for a broad range of operating conditions. However, one drawback of ... En savoir plus
Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is ... En savoir plus
This application illustrates how to model an electric machine, such as a generator, motor, or drive, by exploiting its sector symmetry to reduce the size of the problem. The machine being studied is a simplified electric generator in 3D, based on the geometry used in the generator_2d ... En savoir plus
The present example simulates the steady-state flow in a radial pump using the mixing plane methodology. It solves for the averaged flow resulting from different blade positions of the rotor, thus circumventing the need to perform costly time-dependent simulations. En savoir plus
The acoustic field in a model of an axially symmetric lined aero-engine duct, based on modal sound transmission, is analyzed. The source is generated by a single mode excitation at a boundary. Sources and nonreflecting conditions are applied using port boundary conditions. The model ... En savoir plus
This example models co-electrolysis of H2O and CO2 using a solid oxide electrolyzer cell. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in the H2 and O2 gas flow channels, the energy balance ...
