Microwave drying of foodstuffs is a complex interplay of mass, momentum, and energy transport coupled with large deformation of the solid. To be able to better understand the microwave drying process, a fundamentals-based three dimensional (3D) multiphase porous media based model is ... En savoir plus

Surface Acoustic Waves (SAW) is the acoustic wave that propagates along the surface of the substrate with amplitude decaying exponentially away from the surface. A basic SAW device consists of two IDT’s on a piezoelectric substrate such as quartz. Surface Acoustic Wave can be ... En savoir plus

Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely ... En savoir plus

Simulation on loudspeaker drivers require a conventional fully coupled vibro-acoustic model to capture all effect. An accurate vibroacoustic model can be time-consuming to solve, especially in 3D. In practical applications, this results in poor efficiency concerning the decision-making ... En savoir plus

In our project, we propose an innovative software solution to the problem of electrical arcing risk prediction in high-voltage on-board electronic equipment intended for long-term self-contained use, e.g. in spacecraft conditions. It completely based on so-called “decomposition” approach ... En savoir plus

The effects of sharp corners on the flux distribution in a ferromagnetic core are modeled using COMSOL Multiphysics® to determine the time-domain flux density for an applied field which is uniform in the non-corner section of the core. The frequency spectrum of the flux distribution is ... En savoir plus

The EM optimization of a coarsely discretized model of a microstrip band-pass filter implemented in COMSOL Multiphysics® was realized using two different model configurations. We presented a systematic methodology to find an appropriate 3D EM model configuration on a direct EM ... En savoir plus

The conversion of mechanical energy from environmental vibrations into electrical energy is a key point for powering sensor nodes toward the development of autonomous sensor systems. Piezoelectric energy converters realized in a cantilever configuration are the most studied for this ... En savoir plus

This work presents a method to calculate AC losses in thin conductors such as the commercially available second generation superconducting wires through a multiscale meshing technique. The main idea is to use large aspect ratio elements to accurately simulate thin material layers. For a ... En savoir plus

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... En savoir plus
