Multiphysics Analysis of CO2 Foil Thrust Bearing Characteristics

Treevor Munroe
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 ...

ON, Canada

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 ...

Analysis of Subsea Umbilicals and Cables

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 ...

A Smooth Optical Surface in Minutes

Anthony Beaucamp
Zeeko Ltd
Leicestershire, UK

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 ...

Submarines: Corrosion Protection or Enemy Detection?

David Schaefer
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 ...

Current Transformer Design That Combines Finite Element Analysis and Electric Circuit Simulation

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 ...

Modeling Optimizes a Piezoelectric Energy Harvester Used in Car Tires

Alexander Frey and Ingo Kuehne
Siemens Corporate Technology, Munich, Germany

Siemens is a technology company working with electronics and electrical engineering in industry, energy, and healthcare. Researchers at Siemens Corporate Technology are experimenting with an energy harvesting MEMS (Micro Electro-Mechanical System) generator. In collaboration with Continental AG, they are designing a MEMS device for use as a Tire Pressure Monitoring System (TPMS). The movement ...

Upgrading the Nuts and Bolts of the Electrical Grid for a New Generation

Bruker Energy & Supercon Technologies
Billerica, MA

Migrating the electrical grid to a “smart grid” is usually discussed in terms of IT issues or embedded systems. Yet, just as important updating the “nuts and bolts” of the smart grid. At ABB AB Corporate Research Power Technologies in Sweden, scientists are working to reduce line current and the resulting resistive loss in cables caused by the use of increased voltage in modern transmission ...

Metamaterials Make Physics Seem Like Magic

Metamaterials are manufactured, structured materials that they can interact and manipulate wave phenomena such that objects surrounded by metamaterials are shielded from these waves. In the case of light, metamaterials make these objects ‘invisible’. Researchers throughout the world are applying these materials to many different applications. At NASA Glen Research Center, physicists are ...
