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 ...
mieletec FH Bielefeld
The induction stove was designed to meet a consumer need for better precision and speed than traditional stoves. Designers were tasked with improving the energy efficiency of the induction coils-stovepot interaction considering both the thermal and electromagnetics of the system. Miele, a world leader in domestic appliances and commercial machines, along with researchers from mieletec FH ...
Xi Engineering Consultants Ltd, Edinburgh, UK
Xi Engineering Consultants Ltd specializes in complex vibration issues, like those caused by wind turbines. The meshing of teeth within the gearbox of a wind turbine can cause great vibrations which are perceived as excessive noise. This presents a problem as there are strict regulatory standards throughout Europe and North America limiting permissible noise from these structures. Studying the ...
Tessera Technologies, CA, USA
Removing heat from electronic devices is a necessity that up until now was achieved by rotary fans. Tessera, a company that delivers innovative miniaturization technologies and products for next-generation electronic devices, developed a replacement for rotary fans that can satisfy demanding space and noise constraints. They designed a silent air cooling system that uses an electric field to ...
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 ...

Surface Plasmon Resonance (SPR) is created by surface plasmons, coherent electron oscillations existing between any two materials where the real part of the dielectric function changes sign across the interface. SPR technology is based on the electromagnetic field component of incident light penetrating into a surface and it can be used to detect molecular adsorption on surfaces. Plasmon ...

Shell Global Solutions
Shell Global Solutions UK is conducting research to optimize lubricants for the fuel economy. A problem exists in creating a balance between energy efficient lubricants that decrease friction, and the higher wear created by the thinner oil film in the lower friction lubricant. There are also many points of contact with extremely high pressure, which increases the viscosity of the lubricant, ...
Sharp Laboratories of Europe, UK
There are several kinds of technology that designers at Sharp Laboratories of Europe work to create. From LED lighting, displays, and microfluidic lab-on-a-chip technology, to complex energy systems used in various devices, Sharp needed a new approach to finding the best designs. COMSOL Multiphysics and its add-on products provided the versatility to augment Sharp's research and development in ...
French Atomic and Alternative Energy Commission
Battery management systems (BMSs) are designed to protect the batteries and predict their charge level. They use circuit models often derived from electrochemical impedance spectroscopy (EIS) measurements to construct an equivalent circuit model (ECM) that consists of resistors and capacitors connected both in series and in parallel. Yet, ECMs do not provide any information about important cell ...
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 ...
