Chemical Gradients, Carryover and Mixing in Fluidic Diagnostic Systems
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 ... Read More
Corona effect prediction methodologies for grounded sphere-sphere configurations
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 ... Read More
Modeling MEMS Gyroscopes with COMSOL Multiphysics®
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 ... Read More
An interaction between electromagnetic field and materials: Characterization of mechanical stress in ferromagnetic materials using Eddy currents non-destructive techniques
For more than thirty years the GeePs Laboratory has been working on the numerical simulation of electromagnetic systems through numerous research topics. During this conference, we propose to present a recent problem that has been addressed by the laboratory. This application concerns ... Read More
Optimizing your Femtosecond Laser Processes using a Numerical Simulation based Decision Support Tool
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 ... Read More
COMSOL Multiphysics® thermal simulations of a Mars simulating environment facility
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 ... Read More
Custom Controller Embedded into COMSOL Multiphysics® Magnetic Levitation Model via external MATLAB® file
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 ... Read More
Image based, geometry prescribed CFD of intra-cardiac flows on a dynamic heart phantom
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 ... Read More
Beyond the limits of mass transfer: How pillar electrodes influence electrochemical reactors
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 ... Read More
Optimization of Loudspeakers
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 ... Read More
