Paper based lateral flow assays are widely used as point of care devices for disease diagnostics due to their low cost, short run time and ease of use. Binder molecules specific for certain molecular biomarkers of interest are typically deposited as dots or lines on paper strips, ... En savoir plus
A COMSOL Multiphysics® simulation was used to simulate the behavior of a micro-membrane (Acoustic Pixel) to be used as a potential acoustic transducer. The MEMS and Piezoelectric devices interfaces were used to simulate such transducer. A four-cantilever spring configuration is initially ... En savoir plus
Numerical simulations applied to blood flow together with the imaging processing advances are a powerful tool in the prevention and treatment of some diseases. The inclusion of real data in the numerical blood flow simulations allows the achievement of more realistic and accurate ... En savoir plus
In a laboratory setup a horizontal rod is heated on one side. By natural convection a stable temperature pattern is developed. Using the Nusselt formulation of the natural convection of cylindrical rods, the temperature distribution can be calculated. Only a good match of the simulations ... En savoir plus
Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... En savoir plus
A Dutch firm manufactures a mounting system to fasten roof workmen to the roof of a flat roof building to prevent them from falling down from the roof. The system is mounted to the flat roof afterwards, i.e. after the completion of the thermal insulated roof. Because of the mechanical ... En savoir plus
Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of ... En savoir plus
Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... En savoir plus
Horizontal-Flow Constructed Wetlands (HFCWs) are a particular type of biofilter, and as such they rely mostly on the activity of bacterial communities to treat wastewater. Bacterial growth in HFCWs induces dramatic changes in its hydraulic and hydrodynamic behaviour (bioclogging), which ... En savoir plus
The current work is dedicated to develop a FEM model for compressors using moving mesh. An analytical model is already developed for a classic compressor based on mass and energy balance and is extended to a finned piston compressor. COMSOL Multiphysics® is employed to verify the ... En savoir plus
