This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The ... En savoir plus
Surface plasmon-based circuits are being used in applications such as plasmonic chips, light generation, and nanolithography. The Plasmonic Wire Grating Analyzer application computes the coefficients of refraction, specular reflection, and first-order diffraction as functions of the ... En savoir plus

This model shows how a flow model can be coupled to a process control mechanism. Controlling application parameters according to other application parameters is important within process engineering. Most control mechanisms use the data at a wall or an outlet to control inlet ... En savoir plus
The purpose of this application is to generate response spectra from a time history which can consist of either measured data on a file, or an analytical function. Primarily, the target is to provide input to a response spectrum analysis. The graphs can, however, also be used to ... En savoir plus
Porous materials are frequently represented through periodically arranged microstructures. To compute porous media flow, the macroscale permeability and porosity is used which can be calculated from the creeping flow results through the microscale unit cell. In this application, various ... En savoir plus

This example shows how to model a deep excavation. The main application area of this type of modeling is in civil engineering. In this case, the in situ lateral pressure acting on the retaining wall during the soil excavation is modeled with boundary loads. The soil assumes Drucker ... En savoir plus
Dielectric microspheres can support whispering gallery modes with high optical quality factors. This model illustrates how to compute the different eigenmodes and resonance frequencies. The resonance frequencies are either filtered by their spatial localization in the resonator or by ... En savoir plus
The following example demonstrates techniques for modeling a fluid-structure interaction containing two fluid phases in COMSOL Multiphysics. It illustrates how a heavier fluid can induce movement in an obstacle using the arbitrary Lagrangian-Eulerian (ALE) technique along with the Two ... En savoir plus
