Multiphysics Model for Thermal Management of Packaged Mid-IR Laser
Applications of mid-infrared photonic technologies are fueled by innovative advances in quantum cascade lasers, and other key optical components like MEMS gratings and fiber-optics. The integration of devices into optoelectronic packages for stable operation at high powers poses also ... Read More
Highest Pulsed Magnetic Fields in Science and Technology, Assisted by Advanced Finite-Element Simulation
Thomas Herrmannsdörfer got his PhD in experimental physics from the University of Bayreuth in 1994. In 1995, he received the Research Award of the Emil-Warburg-Foundation while he worked at the DFG-Graduiertenkolleg Bayreuth. From 1995 – 1998 he worked as a scientist at Hahn-Meitner ... Read More
Design of a MEMS Bolometer with Absorptive Element as Piezo-Protein
Bolometer is a thermal infrared sensor used for measuring the intensity of radiation via the heating of a material due to the radiations. A bolometer consists of an absorptive element, a thin layered material, connected to a thermal reservoir. The result is that any radiation received on ... Read More
Implication of COMSOL® to Laser Powered Non-Isothermal Reactors for Pyrolysis in the Gas Phase
The IR CO2 laser powered chemical conversions in the gas phase are intriguing and the researchers’ attention was focused on this transformation a while ago. The method, known as Infrared Laser Powered Homogeneous Pyrolysis, or IR LPHP opened reaction pathways not reached by conventional ... Read More
Modeling a Concentrated Solar Thermal Collector for Methane Dry Reforming
Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... Read More
A Numerical Investigation on Active Chilled Beams for Indoor Air Conditioning
In this study fluid-dynamical and thermal performance of active chilled beams is investigated by 2D and 3D modelling in COMSOL Multiphysics. Three different typologies of those air conditioning systems are considered. Results, obtained for typical range of variation of operational ... Read More
Design of an Electrodynamically Actuated Microvalve Using COMSOL Multiphysics® and MATLAB®
This paper describes the design of a normally closed, electrodynamic microvalve. Magnetic forces between a permanent magnet in the valve cover and a soft magnet in the valve seat hold the valve closed. The combination of electrodynamic actuation and a mechanical restoring spring are ... Read More
PIR Sensor Modeling and Simulation Using COMSOL Multiphysics® and its Ray Optics Module
PIR (Passive Infrared) sensor is the most widely used motion sensor for occupancy detection in building automation applications. Normally, only the binary information indicating presence or absence is used. However, an advanced analysis of the PIR sensor analog signal can results in more ... Read More
Impact of the Forces due to CLIQ Discharges on the New HL-LHC Beam Screen
In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... Read More
Thermal Simulations of a LED Light Using COMSOL Multiphysics
An experimental LED light composed of a multi-chip LED-module, a LED driver and an efficient heat sink, was investigated using COMSOL Multiphysics software and the Heat Transfer Module. In an LED light heat is mainly generated in the LEDs but some amount of heat is generated also in the ... Read More
