Heat pipes are designed to transfer heat efficiently through vaporization, mass transfer, and condensation of a working fluid. They are found in a wide variety of applications where thermal control is of importance, with cooling of electronics being a prominent example. Inside a heat ... En savoir plus
Side reactions and degradation processes may lead to a number of undesirable effects, causing capacity loss in lithium-ion batteries. Typically, aging occurs due to multiple complex phenomena and reactions that occur simultaneously at different places in the battery, and the degradation ... En savoir plus
This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... En savoir plus
This example shows how the mixing capability of a stirred vessel can be evaluated. To efficiently reach the steady operational conditions the turbulent flow is solved for using a frozen rotor analysis, and a following time dependent simulation. When a quasi-steady flow field has ... En savoir plus
The electrochemical cell shown in this model can be regarded as a unit cell of a larger wire-mesh electrode that is common in many industrial processes. One of the most important aspects in the design of electrochemical cells is the current density distributions in the electrolyte and ... En savoir plus
During professional wine tasting, several samples of wine are judged in one session. It is important that each sample is covered, since evaporation of ethanol and water will change the taste. This model simulates the evaporation of ethanol and water from a wine glass. Evaporation of ... En savoir plus
Due to abuse, such as internal or external short circuits or excessive heating, an individual battery cell may go into thermal runaway, during which the battery cell generates a significant amount of heat. If enough heat is transferred between adjacent cells during a thermal runaway ... En savoir plus
Carbon deposition on the surface of solid catalysts is commonly observed in hydrocarbon processing. A known problem is that carbon deposits can impede the activity of catalysts as well as block the flow of gas through a catalyst bed. This example investigates the thermal decomposition ...

This model defines a zero-gap alkaline water electrolyzer, where oxygen and hydrogen gas are evolved in porous gas diffusion nickel felt electrodes, placed adjacent to a porous separator (diaphragm). The geometry defines a unit cell of an electrolyzer stack, in turn comprising two full ... En savoir plus
Copper electrowinning is the process of copper extraction from an electrolyte solution and its deposition at the cathode surface, by passing an external current through the electrolytic cell and using an insoluble anode. During the process, oxygen bubbles are generated at the anode ... En savoir plus
