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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

Optimizing your Femtosecond Laser Processes using a Numerical Simulation based Decision Support Tool

Elise Chevallier1, Vincent Bruyère1, Gaëtan Bernard2, Patrick Namy1
1SIMTEC, Grenoble, France

Laser surface texturing has emerged as a promising texturing technique due to properties such as excellent repeatability, non-contact process, the ability to achieve small-size features and high-quality finishing. The work described here is part of the H2020 research program called SHARK ... Mehr lesen

COMSOL Multiphysics® thermal simulations of a Mars simulating environment facility

Abhilash Vakkada Ramachandran1, María-Paz Zorzano2, Javier Martín-Torres3
1Luleå University of Technology
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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

Optimization of Loudspeakers
