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 ...

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, ...

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, ...

Multiphysics Analysis of a Burning Candle

Luke T. Gritter, Sergei Yushanov, Jeffrey S. Crompton, and Kyle C. Koppenhoefer

AltaSim Technologies, Columbus, Ohio

Using COMSOL Multiphysics, AltaSim Technologies were able to predict the temperature distribution and flow pattern of a burning flame during steady state candle burning. In a burning candle, local temperatures in the flame exceed 1400 °C. The heat transfer would include radiation, conduction, and convection components while the low melting point of the candle wax would cause a local phase ...

Analysis and Simulation of Rock Properties

VSG, Burlington, MA, USA

VSG provides high-performance 3D visualization toolkits and software for a number of industries, including materials science and geosciences. One application of their technology is with American oil and gas reserves. The difficulty of accessing these sites has forced the industry to turn to the technique of injecting fluid under pressure into rock deposits. This technique requires knowledge of ...

The Burning Need for Modeling

Gianluca Argentini
Riello Burners
Legnago, Italy

Riello Burners manufactures high-efficiency low maintenance burners for use in residential and commercial heating applications, as well as in industrial processes. Proper ventilation is crucial for a burner because it maintains appropriate air flow into the combustion head where the flame is located. When designing the fan for any burner, there must be a balance between a configuration which ...

Easy and Accurate Measurement of Blood Viscosity

Microvisk Technologies, North Wales, UK

Microvisk Technologies develops and manufactures devices for measuring blood viscosity using the power of Micro Electronic Mechanical Systems (MEMS) and a radical new technique stemming from futuristic research on microtechnology. Older hand-held devices on the market work by inducing a chemical reaction that is picked up by electrodes coated with componds. The MEMS-based micro-cantilever ...
