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 ... En savoir plus
This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... En savoir plus
Topology optimization can result in novel designs due the extreme design freedom associated with the method. Conventional manufacturing techniques impose constraints on the geometry which are often violated by topology optimization. This model demonstrates how the milling constraint ... En savoir plus
In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the solid catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed, by finding the optimal ... En savoir plus
