Simulation-Based Design of New Implantable Hearing Device

Patrik Kennes
Cochlear Technology Centre, Mechelen, Belgium

Cochlear Technology Centre Europe (CTCE) develops new technology for hearing implants. Their current work is with a new type of hearing implant, a Direct Acoustic Cochlear Implant called CodacsTM. This product imposes structural, pressure waves directly to the cochlea, stimulating it this way, as opposed to amplifying sound. Using COMSOL Multiphysics, the team was able to test the many ...

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 ...

Modeling of Laminar Flow Static Mixers

Nagi Elabbasi, Xiaohu Liu, & Stuart Brown
Veryst Engineering LLC, Needham, MA, USA

Mike Vidal & Matthew Pappalardo
Nordson EFD, East Providence, RI, USA

Veryst Engineering, a company that provides consulting in engineering design and product manufacturing, has collaborated with Nordson EFD, one of the leading manufacturers of precision dispensing systems, to optimize their static mixers. Static mixers are inexpensive and efficient mechanisms for mixing laminar viscous fluids, where molecular diffusion is minimal. Here, the fluids must be ...

Multiphysics Simulations Help Track Underground Fluid Movements

A. Haas, H. Mahardika, M. Karaoulis, and A. Revil
Colorado School of Mines, USA

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...

Sea Floor Energy Harvesting

Nagi Elabbasi, Brentan Alexander, and Stuart Brown

Veryst Engineering, Needham, MA, USA

Veryst Engineering has provided design solutions for a variety of industries in the field of energy harvesting. One of their current projects is working on ocean floor sensors, used in naval applications, environmental monitoring, earthquake monitoring, and oil exploration, which presently run on battery-power requiring expensive battery replacement or recharging. Veryst is developing a ...

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 ...

Keeping LEDs Cool Gets More Manageable Through Simulation

Aulis Tuominen and Mika Maaspuro
University of Turku
Turku, Finland

Toni Lopez
Philips Research
Eindhoven, The Netherlands

Sami Yllikäinen
Hella Lighting Finland Oy
Salo, Finland

Raimo Laitinen
Helvar Oy Ab
Karkkila, Finland

Light-emitting diodes (LEDs) offer many benefits over incandescent lighting, such as long life spans and high luminous efficiency, and they are environmentally friendly. One of the drawbacks, however, is that LEDs need to operate at the lowest possible temperatures and this must be carefully regulated. Researchers at Business and Innovation Development Technology at the University of Turku in ...

Multiphysics Analysis of CO2 Foil Thrust Bearing Characteristics

Treevor Munroe
Knolls Atomic Power Laboratory, Niskayuna, NY

Knolls Atomic Power Laboratory (KAPL) is a research and development facility supporting the United States Naval Nuclear Propulsion Program. KAPL recently collaborated with Bettis Atomic Power Laboratory to test a supercritical carbon dioxide (S-CO2) Brayton power cycle system. The system was designed to operate at high speed and high gas pressure, which means the turbine shaft bearings must ...

Cluster Simulation of Refrigeration Systems

Stephen Codyer & Mehdi Raessi
Department of Mechanical Engineering
UMass Dartmouth
Dartmouth, MA

Jessica Currie & Vladimir GoldsteinSunwell Technologies, Inc., Woodbridge
ON, Canada

Sunwell Technologies Inc. produces and distributes the slurry ice (Deepchill™) that is an environmentally-friendly way to refrigerate foods and other items in trucks and the like. They commissioned the Computational Multiphase Flows group at the University of Massachusetts, Dartmouth (UMass Dartmouth) to provide simulation support to the experimental investigations performed by Sunwell. Known ...

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 ...
