Chemical Gradients, Carryover and Mixing in Fluidic Diagnostic Systems

Matthew Hancock1, Andrew Spann1, Andrew Fiore1
1Veryst Engineering, Needham, MA, United States

Recent events underscore the importance of rapid diagnostic tests for detecting viruses such as the SARS-CoV-2 coronavirus or for screening cancer biomarkers. Many fluidic-based diagnostics applications require careful control of chemical and biological species concentrations. In this ... En savoir plus

Corona effect prediction methodologies for grounded sphere-sphere configurations

Agurtzane Etxegarai1, Manuel de la Hoz1, Ane Miren Larrea1, Javier Mazón1
1University of the Basque Country UPV/EHU

In the manufacturing of high voltage electrical equipment, an important step to guarantee a right dielectric design can be carried out through the prediction of a possible occurrence of the corona effect or, in the worst case, of dielectric breakdown, preferably in early stages. For this ... En savoir plus

Modeling MEMS Gyroscopes with COMSOL Multiphysics®

James Ransley1, Nagi Elabbasi2
1Veryst Engineering
2Veryst Engineering, Needham, MA, United States

MEMS gyroscopes are typically challenging to model due to the variable length scales present in the device (typically 1000:1) and because the devices themselves are highly sensitive to both environmental and manufacturing process induced deviations from the ideal geometry. In this paper ... En savoir plus

2Centro de Astrobiología (CSIC-INTA), Torrejón de Ardoz & School of Geosciences, University of Aberdeen
3Instituto Andaluz de Ciencias de la Tierra (CSIC-UGR) & School of Geosciences, University of Aberdeen & Luleå University of Technology

This work describes the implementation with COMSOL Multiphysics® of a thermal simulation of a space environmental chamber, the SpaceQ chamber [1]. Space environment facilities are needed to simulate on Earth the expected performance of hardware and instrumentation that shall operate in ... En savoir plus

Custom Controller Embedded into COMSOL Multiphysics® Magnetic Levitation Model via external MATLAB® file

Adam Krzysztof Pilat1, K.Słowik1
1AGH University of Science and Technology, Department of Automatic Control and Robotics, Mickiewicza 30, 30-059 Krakow, Poland

The right way to design dedicated controller for a particular device or process is to compute an adequate and representative model. In the case of Magnetic Levitation Systems, the mathematical modelling via ordinary differential equations is limited by the analytical functions ... En savoir plus

Image based, geometry prescribed CFD of intra-cardiac flows on a dynamic heart phantom

Rasmus Hvid1, Marie Sand Traberg1
1Technical University of Denmark, department of health technology, Lyngby, Denmark

Introduction: The current gold standard for measuring intra-cardiac blood flow is cardiac magnetic resonance (CMR) and Color-Doppler ultrasound [ref1]. The presented simulation pipeline extracts heart wall motion from medical imaging and simulates the intra-cardiac blood flow as an ... En savoir plus

Beyond the limits of mass transfer: How pillar electrodes influence electrochemical reactors

Michiel De rop1, Jonas Hereijgers1, Tom Breugelmans1
1University of Antwerp, Antwerp, Belgium

Electrochemistry is inherent a surface process, requiring the transport of reagents towards the electrode surface. In electrochemical reactors this typically results in mass transfer limitation problems, limiting the yield and efficiency of the reactor. While the academic community is ... En savoir plus

Optimization of Loudspeakers

A.J. Svobodnik1, T. Nizzoli 1, F.L. Redl 1
1Mvoid Group, Karlsruhe, Germany

Loudspeakers, specifically electrodynamic transducers with enclosures, are used almost everywhere in our life. Transportation of acoustic information is vital for humans since the very beginning of the human evolution. Hence, reproduction of acoustics has a long tradition in engineering ... En savoir plus
