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 ...
Nanoresonators Get New Tools for Their Characterization
J. Yang, M. Perrin, P. Lalanne CNRS, France
Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter light and interact with their surrounding environment are not ...
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 ...
Optimized Heating Process with Uniform Coating
Mika Judin Rautaruukki Oyj Hämeenlinna, Finland
Rautaruukki Oyj supplies metal-based components and systems to the construction and mechanical engineering industries, where process engineer, Mika Judin, works with optimizing their coating technologies. When coating rolled metal with paint, it is important that the coating be applied such that it is not discolored or damaged, and that it is ...
Reduced-Weight Reaction Sphere Makes Way for Extra Satellite Payload
Leopoldo Rossini, Emmanuel Onillon, & Olivier Chetelat CSEM SA, Neuchatel, Switzerland
CSEM is a private applied research and development center specializing in micro-technology, system engineering, micro-electronics, and communications technologies. One of their latest projects is working on minimizing the weight of satellite attitude control systems as every gram of payload matters when launching a satellite into orbit (€15,000 ...
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 ...
How Reclosers Ensure a Steady Supply of Power: It’s All in the Magnet
O. Craciun, and colleagues ABB AG Ladenburgh, Germany
When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process ...
Convective Heat Transfer with Pseudo-Periodicity
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the outlet boundary from the previous solution is mapped to the ...
Domain Activation and Deactivation
Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®.
Homogenization in a Chemical Reactor
This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time-dependent solver, then restart it with an initial value obtained ...
