Simulation-Based Engineering Fosters Innovation and Invention

Ozgur Yildirim and Zihong Guo
Intellectual Ventures
Bellevue, WA

Simulation-based engineering is the key to shortening time to market for innovations. Intellectual Ventures, in Bellevue, WA, is reaping the benefits of using COMSOL Multiphysics to accelerate their workflow from design study to prototype, and then on to their customers as inventions through various partnerships and licensing programs. Projects where COMSOL has been used include the beam ...

Modeling Scar Effects in Electrical Spinal Cord Stimulation

Kris Carlson, Dr. Jay Shils & Dr. Jeffrey Arle
Lahey Clinic
Burlington, MA

The Neuromodulation Group at Lahey Clinic conducted a study based upon spinal cord stimulation (SCS). SCS involves implanting a series of electrodes that apply electric potential to the spine, interfering with pain signaling circuitry. It’s used to alleviate chronic back and leg pain. Although the treatment remains effective for years, the electrodes must be reprogrammed through trial and error ...

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 applied evenly. Heat transfer therefore needs to be ...

The Science of Water Screening

Ehrich Shaw
Johnson Screens
New Brighton, MN

Johnson Screens® are the manufacturers of steel screens that impede debris from lakes and rivers from entering pipes and valves that will utilize the water. Their task is to provide application-specific screens that must be customized to the environment they are operating in. Often this means taking into account the characteristics of the debris they are to remove, the depth at which the screen ...

Shape Changing Lubricants

Robert Ian Taylor
Shell Global Solutions
Cheshire, UK

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, ...

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 per kilogram). CSEM hopes to accomplish this task ...

Battery Simulation Propels Electric Cars in China

Dr. Songrui Wang

Tianjin Institute of Power Sources, Tianjin, China

Dr. Songrui Wang is a researcher at The Tianjin Institute of Power Sources, involved in battery testing and evaluation for design recommendations on safety. She analyzes the risk of potential fire hazards associated with lithium ion batteries, which are fast becoming the most popular sort of battery for vehicles, mobile devices, and many other applications. COMSOL Multiphysics was used to ...

Pumping and Injecting from a Single Borehole

Prof. Martin Sauter, Ph.D Student Yulan Jin, and Assoc. Prof. Ekkehard Holzbecher
Georg-August-University, Göttingen, Germany

Professor Dr. Martin Sauter leads a group at the University of Göttingen in research on hydrogeology. Cooperating with Hölscher Wasserbau, a leading German dewatering company, the group is studying düsensauginfiltration (DSI), which is a technique for lowering groundwater levels at mining or construction sites. Traditionally, dewatering involves the transportation of water away from the site, ...

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 ...
