In many medical procedures and tests, it is necessary to isolate cells of interest for further analysis. Microfluidics has revolutionized the way in which these tests are conducted enabling, for example, the ability to detect cancer from a blood sample. One of the most promising microfluidic techniques to separate and concentrate cells is called inertial focusing. The equilibrium positions for a ...

Radiation therapy targeting in cancer treatment involves many uncertainties, including the movement of targeted sites due to breathing and the like. Magnetic resonance imaging (MRI) can accurately identify the location of a tumor in soft tissue, but unfortunately its magnetic field can interfere with radiation treatment delivered by a linear particle accelerator (Linac). A team of researchers at ...

Modern cars offer a wide range of complex functionality that comes with several design challenges. This story discusses some of the necessary updates to a roof module in a premium car and the charging system of an electric car. The roof module of a particular model houses several components. 90% of the generated heat goes into its printed circuit board (PCB), so temperature control is vital for ...

Professor Mark Reed and his team at Yale University are using COMSOL Multiphysics to develop a MEMS-based solution for detecting bacteria in blood. Called the aScreen, it will provide analyses speedily, accurately, and cost-effectively. Such a device would greatly help the food industry in improving meat quality and reducing the risk for infections. Current methods take too long for most food ...

This is an application brief describing the concept of Conjugate Heat Transfer, which is important in many industrial processes, such as quenching. In this brief, they simulate the heat transfer with and without phase transformation to analyze the rate of heat dissipation with respect to the flow conditions of the coolant media. The fluid flow conditions could then be modified to produce a ...

Esaote S.p.A. produces medical diagnostic systems, including the manufacturing and sales of ultrasound imaging systems. Lorenzo Spicci and Marco Cati are researching ways to improve ultrasound probes to maximize their performance, knowing a smaller, more effective machine could make this technology more accessible. They used COMSOL Multiphysics to create a model of these transducers, coupling ...
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 ...
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 ...

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 ...

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 deployed through tight-radius reels. A challenge for ...
