Analysis of Subsea Umbilicals and Cables

Tim Poole, JDR Cables, Cambridgeshire, UK
and
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 ...

Numerical Simulation-Based Topology Optimization Leads to Better Cooling of Electronic Components in Toyota Hybrid Vehicles

Toyota Research Institute of North America, MI, USA

The Toyota Research Institute in Ann Arbor drives cutting-edge research in energy efficiency, mobility infrastructure, and safety. Here, Ercan Dede and his team are designing heat sinks (or cold plates), which are affixed to fragile electrical systems and other applications in Toyota’s hybrid vehicles. Their simulations simulate the cold plate’s topology for improved cooling efficiency ...

Sonar Dome Vibration Analysis

Francesca Magionesi
INSEAN
Italy

There has been a recent move towards utilizing bulbous bows on ships to house different types of sonar systems, but it is not definite how much structural vibration might interfere with the functioning of a transducer array inside the sonar dome. INSEAN, the National Institute for Studies and Experiments of Naval Architecture in Italy, needed a way to simulate what is happening when the turbulent ...

Surface Plasmon Resonance

Sergei Yushanov, Jeffrey S. Crompton, Luke T. Gritter, and Kyle C. Koppenhoefer
AltaSim Technologies
Columbus, OH
USA

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 ...

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 of ...

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 Inertial Focusing in Straight and Curved Microfluidic Channels

J. Martel and M. Toner
Biomems Resource Center
Massachusetts General Hospital
USA

N. Elabbasi, D. Quinn, and J. Bergstrom
Veryst Engineering
USA

In many medical procedures and tests, it is necessary to isolate cells of interest for further analysis. Microfluidics has revolutionized the way in which these tests are conducted enabling, for example, the ability to detect cancer from a blood sample. One of the most promising microfluidic techniques to separate and concentrate cells is called inertial focusing. The equilibrium positions for a ...

Highly Accurate Li-ion Battery Simulation

Mikael Cugnet
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 ...

Metamaterials Make Physics Seem Like Magic

Naval Postgraduate School
Monterey, CA

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 ...

Optimizing Ultrasound Piezo-disk Transducers

Lorenzo Spicci & Marco Cati
R&D Department
Esaote S.P.A.
Florence, Italy

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 ...
