The purpose of this model is to visualize the electric potential in an electrochemical cell, for example a battery. This is done at OCV and during operation. In a battery, this would correspond to OCV, discharge, and recharge. The potential profile is explained both for cells with planar ... Mehr lesen
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Mehr lesen
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... Mehr lesen
This model demonstrates how to optimize the charging profile of a battery using gradient based optimization. The optimization solver minimizes the time required for charging the battery from 0% to 90% state of charge, while at the same time constraining the amount lithium inventory lost ... Mehr lesen
Bei der Bewertung der Wirksamkeit von Behandlungen für Augenkrankheiten können Modellierung und Simulation für die pharmakokinetische Analyse verwendet werden. Dazu wird die Medikamentenkonzentration und ihre Ausbreitung im Auge im Lauf der Zeit visualisiert. In diesem vereinfachten ... Mehr lesen
The liquid electrolyte in lithium-ion batteries (LIBs) typically consists of a lithium salt, such as LiPF6, dissolved in one or several solvents. Commercial LIBs commonly employ a mix of multiple hydrocarbon-based solvents along with additional additives. In an electrolyte consisting of ... Mehr lesen
This slide deck introduces and demonstrates the modeling capabilities for crystallization and precipitation processes in COMSOL using the Size-Based Population Balance interface and Precipitation in Fluid Flow coupling feature released in 6.3. Mehr lesen
This model file was used for creating the plots featured in the blog post "How to Model Ion-Exchange Membranes and Donnan Potentials". Mehr lesen
This application uses the shrinking core model to study the reduction of iron ore pellets. A 1D model of a packed bed containing iron ore pellets is modeled. The bed filling pellets initially consists of solid phase FeO. The pellets are reduced by CO, and the solid core shrinks leaving a ... Mehr lesen
This example computes the power losses in a lithium-ion battery when exposed to high current pulses in a hybrid pulse power characterization (HPPC) test. Power loss contributions stemming from different phenomena are analyzed, as well as the total power losses pertaining to the ... Mehr lesen
