Shell-and-tube heat exchangers are commonly used in oil refineries and other large chemical processes. In this model, two separated fluids at different temperatures flow through the heat exchanger, one through the tubes (tube side) and the other through the shell around the tubes (shell ...

Échelle spectrographs are commonly used in astronomy for high-resolution analyses of stellar atmospheres and for precision Doppler velocimetry. This tutorial simulates a "white pupil" form of this instrument. It makes use of several parts from the COMSOL Part Library and demonstrates the ... En savoir plus
Seawater intrusion is a critical issue in coastal regions, where it endangers both freshwater supplies and the overall quality of groundwater. This example showcases seawater intrusion in a coastal aquifer where a pumping well is located at some distance from the shoreline. The model ... En savoir plus
In this example, the brittle fracture of a holed plate with a notch is modeled using a phase-field damage model. The geometry of the plate is set up so that a mixed-mode fracture is induced, with dimensions and material properties taken from experimental data. The example shows how to ... En savoir plus
This model analyzes a piezoelectric microelectromechanical system (MEMS) speaker. The speaker, composed of four triangular membranes, uses a layer of lead zirconate titanate (PZT) material with two electrodes on top of a silicon layer as actuators. The triangular membranes are separated ... 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 model analyzes the electromagnetic, mechanical, and acoustical characteristics of the OWS-1943T-8CP (discontinued) speaker. Beside certain details, the geometry, material properties, and measurements are copyright by Ole Wolff. Starting from the geometry of the speaker, an ... En savoir plus
This model analyses the noise generated by an electric motor during its operation at different speeds of rotation. The type of electric motor analyzed, a permanent magnet synchronous motor (PMSM) uses permanent magnets in the rotor and a variable frequency current traveling through the ... En savoir plus
This is a model of the heating process in a microwave oven. The distributed heat source is computed in a stationary, frequency-domain electromagnetic analysis. This is followed by a transient heat transfer simulation showing how the heat redistributes in the food. En savoir plus
In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... En savoir plus
