This tutorial models how the relative humidity of the inlet gases impacts the performance of a low-temperature polymer electrolyte membrane-electrode assembly. The model includes humidity-dependent ionomer (electrolyte) conductivities, gas phase mass transport and water ionomer ... En savoir plus
A stationary 3D model of a generic fuel cell cathode describing the mass fraction distribution of oxygen, water, and nitrogen, as well as the current distribution. The model uses Darcy's Law to describe convection, and couples this to Maxwell-Stefan diffusivities to also describe mass ... En savoir plus
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
The flow around the Eppler 387 airfoil is computed with the SST turbulence model both with and without the transition model. The reuslts are compared with experimental values. En savoir plus
This model demonstrates the Lithium-Ion Battery interface for studying the discharge and charge of a lithium-ion battery for a given set of material properties. The geometry is in one dimension and the model is isothermal. Battery developers can use the model to investigate the influence ... En savoir plus
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... En savoir plus
This is a tutorial example, showing how to work with pretensioned bolts. Various aspects of bolt modeling are explored: Modeling bolts as solids or by beams Connections of beams to solid components Bolts ended by nuts or by internal threads in the attached component Import of bolt and ...

This benchmark model simulates three different heterojunction configurations under forward and reverse bias. It shows the difference in using the continuous quasi-Fermi level formulation versus the thermionic emission formulation for the charge transfer across the heterojunction. The ... En savoir plus
This tutorial shows the analysis of a car cabin in order to study the performance of a sound system in the low to mid frequency range. The cabin is of a typical sedan interior, that is, the inside of a hard-top family car. The model studies the frequency response at the location of a ... En savoir plus
Deposition of metallic lithium on the negative electrode in preference to lithium intercalation is known to be a capacity loss and safety concern for lithium-ion batteries. Harsh charge conditions such as high currents (fast charging) and/or low temperatures can lead to lithium plating. ... En savoir plus
