Optimization of a Catalytic MicroreactorOptimization of a Catalytic Microreactor

In this model, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the catalyst. The model calculates the maximize total reaction rate of the solute for a given total pressure...

Planar Transformer on a PCBPlanar Transformer on a PCB

A planar transformer is a transformer that is integrated onto a printed circuit board (PCB). They can either be manufactured as standalone devices, or integrated into the PCB of a module. The planar structure improves the cooling...

Propagation of a 3D Gaussian Beam Laser PulsePropagation of a 3D Gaussian Beam Laser Pulse

Laser systems are an important application area in modern electronics. There are several ways to generate a laser beam, but they all have one thing in common: the wavelength is determined by the stimulated emission, which depends on...

RF Introductory Tutorial: Step by Step Modeling of a Dipole AntennaRF Introductory Tutorial: Step by Step Modeling of a Dipole Antenna

This is an introductory tutorial that shows how to model a dipole antenna using the COMSOL RF Module. A dipole antenna is one of the simplest antenna structures, and many radiating structures can be modeled in similar ways to 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...

RF-Heated Hot Wall Furnace for Semiconductor ProcessingRF-Heated Hot Wall Furnace for Semiconductor Processing

Furnace reactors are used in the fabrication of semiconductor industry to grow layers on the wafers. These can also be used for epitaxial growth, which is a key technology for fabrication of electrical devices.For the wide band gap...

Schematic PumpSchematic Pump

The rotating machinery application mode makes it possible to model moving rotating parts in for example stirred tanks, mixers and pumps. This model exemplifies this in the Chemical Engineering Module. The application mode takes care...

Structural Analysis of an Elbow BracketStructural Analysis of an Elbow Bracket

This model performs a structural analysis of an elbow bracket of steel fixed at one end. The component is part of a support mechanism and is subjected to both mechanical loads and thermal loads. This tutorial model takes you through...

Structural and Fatigue analysis of a Frame with CutoutStructural and Fatigue analysis of a Frame with Cutout

In this model, a frame member with a cutout causing stress concentrations is studied. Concern has arisen that fatigue cracks might occur at the cutout as the service loads are increased. Since the loading is random in nature, it needs...

Temperature distribution in an IC packageTemperature distribution in an IC package

Designs of circuit boards might have to consider the placements of surface-mount devices, which produce heat. In this model, a heat producing voltage regulator, which reaches temperatures above 70 C is placed close to a surface mounted...
