Hydrocarbon Dehalogenation in a Tortuous MicroreactorHydrocarbon Dehalogenation in a Tortuous Microreactor

Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a...

LoudspeakerLoudspeaker

This is a model of a loudspeaker of the dynamic cone driver type, common for low and medium frequencies. The instructions walk you through modeling its electromagnetic, structural, and acoustic properties. The output from the model...

Microresistor BeamMicroresistor Beam

The example illustrates the ability to couple thermal, electrical, and structural analysis in the one model. This particular application displaces part of a beam by passing a current through it; the current generates heat, and the...

Model of an RFID SystemModel of an RFID System

RFIDs are used in a multitude of applications such as tracking or identifying consumer products and their packaging. An RFID system consists of two main parts: A tag or transponder with a printed circuit-board (PCB) antenna A reader...

Phase ChangePhase Change

This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, from solid to liquid for instance, energy is added to the solid. Instead of creating a temperature...

Porous Reactor with Injection NeedlePorous Reactor with Injection Needle

This model treats the flow field and species distribution in an experimental reactor for studies of heterogeneous catalysis. The model exemplifies the coupling of free and porous media flow in fixed bed reactors. The reactor consists...

Process Control using a PID ControllerProcess Control using a PID Controller

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...

RF Introductory Tutorial: Step by Step Modeling of Microwave HeatingRF Introductory Tutorial: Step by Step Modeling of Microwave Heating

This is an introductory tutorial that shows how to model RF heating using COMSOL. RF heating occurs whenever an electromagnetic wave interacts with matter. Typical areas of interest include modeling of microwave ovens, cell phone...

Semiconductor DiodeSemiconductor Diode

A semiconductor diode consists of two regions with different doping: a p-type region with a dominant concentration of holes, and an n-type region with a dominant concentration of electrons. The model presented here formulates the...

Sheet Metal Forming by a Spherical PunchSheet Metal Forming by a Spherical Punch

A common sheet metal forming process is where a punch is used to deform a plate clamped between two jaws. This axi-symmetric contact model simulates the deformation of an elasto-plastic circular plate being bent by a spherical...
