This is an application brief describing the concept of Conjugate Heat Transfer, which is important in many industrial processes, such as quenching. In this brief, they simulate the heat transfer with and without phase transformation to analyze the rate of heat dissipation with respect to the flow conditions of the coolant media. The fluid flow conditions could then be modified to produce a ...
Cochlear Technology Centre, Mechelen, Belgium
Cochlear Technology Centre Europe (CTCE) develops new technology for hearing implants. Their current work is with a new type of hearing implant, a Direct Acoustic Cochlear Implant called CodacsTM. This product imposes structural, pressure waves directly to the cochlea, stimulating it this way, as opposed to amplifying sound. Using COMSOL Multiphysics, the team was able to test the many ...
Lorenzo Spicci & Marco Cati
Esaote S.p.A. produces medical diagnostic systems, including the manufacturing and sales of ultrasound imaging systems. Lorenzo Spicci and Marco Cati are researching ways to improve ultrasound probes to maximize their performance, knowing a smaller, more effective machine could make this technology more accessible. They used COMSOL Multiphysics to create a model of these transducers, coupling ...
Knolls Atomic Power Laboratory, Niskayuna, NY
Knolls Atomic Power Laboratory (KAPL) is a research and development facility supporting the United States Naval Nuclear Propulsion Program. KAPL recently collaborated with Bettis Atomic Power Laboratory to test a supercritical carbon dioxide (S-CO2) Brayton power cycle system. The system was designed to operate at high speed and high gas pressure, which means the turbine shaft bearings must ...

Jessica Currie & Vladimir GoldsteinSunwell Technologies, Inc., Woodbridge
Sunwell Technologies Inc. produces and distributes the slurry ice (Deepchill™) that is an environmentally-friendly way to refrigerate foods and other items in trucks and the like. They commissioned the Computational Multiphase Flows group at the University of Massachusetts, Dartmouth (UMass Dartmouth) to provide simulation support to the experimental investigations performed by Sunwell. Known ...
Tim Poole, JDR Cables, Cambridgeshire, UK
Mark Yeoman, Continuum Blue, Hengoed, UK
JDR Cables designs-to-spec and manufactures subsea umbilical systems of cables and reelers for the oil and gas and renewable energy industries. In these designs, the harsh environments of deep water pressure, wind and waves, as well as the rough ocean floor must all be considered, along with the forces acting on cables from being pulled and deployed through tight-radius reels. A challenge for ...

Global Lightning Protection Services A/S, Lejre, Denmark
Søren Find Madsen, Global Lightning Protection Services A/S, Lejre, Denmark Global Lightning Protection Services A/S (GLPS) is an engineering consultant firm specializing in lightning protection. Their current research involves protecting wind turbines from lightning strikes, which can interfere with the electronic equipment in the housing of the turbines. To analyze optimum design, GLPS ...
University of Duisburg-Essen, Duisburg, Germany
Germany's Technical Center for Ships and Naval Weapons, Bundeswehr, Germany
Submarines create underwater electric potential (UEP) signatures when using corrosion protection systems. These signatures are detectable by enemy vessels, an undesirable effect of the corrosion protection. Germany’s Technical Center for Ships and Naval Weapons (WTD 71) has worked with the Laboratory for General and Theoretical Electrical Engineering (ATE) at the University of Duisburg-Essen to ...
Zeeko Ltd is a technology company that manufactures corrective polishing machines for optics and other surfaces. They are presently researching fluid jet polishing (FJP), which pumps a mixture of water and abrasive particles through a nozzle onto a work piece. Unfortunately, FJP tends to introduce waveforms on to the polished surfaces, which in turn causes serious problems with optics. It is ...
Dr. Rolf Disselnkötter
ABB AG, Ladenburg, Germany
Transformers have been around for quite a while but their fundamentals are still being investigated by ABB in Ladenburgh, Germany. The ABB Corporate Research Centre is currently developing sophisticated magnetic sensors, using finite element analysis (FEA) to investigate the way in which external electrical sources and loads impact a magnetic subsystem like a transformer core. Their goal is to ...
