Using Multiphysics Simulation to Prevent Building Damage

P. Sekki
Vahanen Group, Finland

In addition to surviving normal winters, a strong building must be able to survive the worst winters expected in a 50-year period. When moisture and contaminants enter concrete foundations, they create the risk of cracking or other structural damage once the soil or foundation freezes. Vahanen Group specializes in building services and performs quality and risk assessments to make sure that ...

Simulation Turns Up the Heat and Energy Efficiency at Whirlpool Corporation

N. Garcia-Polanco
Whirlpool Corporation, Italy

Engineers working on a joint research project between Whirlpool Corporation and the European initiative GREENKITCHEN project are using simulation to improve the energy efficiency of domestic ovens. Since only ten to twelve percent of the total energy expended by an oven is actually used to heat the food, the researchers had plenty to investigate. Using COMSOL Multiphysics® software and the Heat ...

Simulation Enables the Next Generation of Power Transformers and Shunt Reactors

L. Jovelli
Siemens, Brazil

From power generation to its distribution to end users, power transformers and shunt reactors are used throughout the electrical grid for voltage conversion and to absorb reactive power. At Siemens Brazil in Jundiai, São Paulo, designers are using multiphysics simulation to verify that grid-integrated transformers and shunt reactors can handle increasing power demands without overheating in ...

Optimizing Hematology Analysis: When Physical Prototypes Fail, Simulation Provides the Answers

D. Isèbe
HORIBA Medical, France

Hematology analysis, the analysis of a blood sample to determine a variety of hematological parameters, is a major factor in diagnostic and treatment decisions for blood diseases. Accurate blood analysis requires counting and sorting different cells in a sample to measure their sizes and distributions. HORIBA Medical, a company that supplies medical diagnostic equipment, uses COMSOL Multiphysics ...

Actuation Technique for Miniature Robots Developed using Multiphysics Simulation

P. Lazarou, C. Rotinat
CEA LIST, France

Robotic devices for minimally invasive surgery procedures require flexible tools and careful actuation. But most robotic surgery devices are bulky, expensive, and physically draining for surgeons to operate for long periods of time. At the French Atomic and Alternative Energies Commission (CEA LIST), researchers are investigating miniature phase-change actuators that will reduce the strain ...

Meeting High-Speed Communications Energy Demands Through Simulation

S. Lei, R. Enright, R. Frizzell, D. Hernon
Bell Labs, Ireland

The information and communication technology industry needs new energy-efficient devices that can keep up with the explosive growth in data traffic of the last few years. Bell Labs, the research arm of Alcatel-Lucent, is taking the lead in an initiative to reduce the carbon footprint of high-speed communication devices and platforms by investing in new methods for cooling electronics and ...

Simulation Software Brings Big Changes to Cable Industry

M. Bechis
Prysmian, Italy

The design and testing of high-voltage cables for terrestrial and submarine applications is paramount to Prysmian's business model. A fundamental challenge in designing power transmission systems is optimizing the cables so that they can reliably deliver the required steady-state current while remaining at, or preferably below, the maximum permissible operating temperature. Incorporating ...

Patterning Cells with the Flip of a Switch for Bioengineering Applications

G. Zhang
Clemson U, SC, USA
J. Brcka, J. Faguet, E. Lee
Tokyo Electron, TX, USA

Dielectrophoresis (DEP) is a method of patterning cells and particles used in medical, electronics, and energy applications. When an electric field is applied to an array of cells or dielectric particles suspended in a medium, they become polarized, causing movement that reorganizes the particles. This is an efficient way to assemble materials layer by layer at the nanoscale, and is sometimes ...

Gaining Insight into Piezoelectric Materials for Acoustic Streaming

G. Potter
SUNY Albany, NY, USA

Many sensors, such as flow sensors and those used in medical diagnostics, rely on microfluidic devices. However, mixing and pumping fluids becomes challenging because of the small size of these devices. As an alternative to traditional actuation methods, surface acoustic waves (SAWs) can be used to create fluid streaming. Through a collaboration between SUNY Albany and SEMATECH, researchers have ...

Enhancing Transmission Line Performance: Using Simulation to Optimize Design

J. Leman
POWER Engineers, MA, USA

Designing power transmission lines requires accounting for many factors: mechanical stress due to environmental conditions and hardware loads, performance testing, and--of course--electrical analysis. Transmission line hardware contains both insulating and conducting assemblies. One common electrical phenomenon is called corona discharge, which occurs when electric fields near the surfaces of ...
