A hyperelastic seal is pulled over a metal ring in a coffee machine for maintenance reasons. The force needed to pull the hyper elastic seal over the part is too high and should be reduced for maintenance reasons. Using the COMSOL Multiphysics® Structural Mechanics Module, and using the non-linear hyperelastic for the stick slip movement, a reliable simulation was generated. It resulted in an ...

SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units using cryogenic optical calibration sources. To support this work we have used COMSOL Multiphysics® to model the ...

The hills of South-Limburg, the Netherlands, are crisscrossed with underground limestone mines. These "caves" are not equally stable, and can be dangerous. With COMSOL Multiphysics® a stability assessment has been made. The first study examines the full stress and displacement profile without excavation. In a second study the domains of the corridors are excluded, to represent the excavation ...

We theoretically studied the microwave coplanar line of different geometry based on MgO substrate with a thin (30 nm) ferroelectric layer under the external electric field using the environment of 3D modeling in COMSOL Multiphysics®, RF Module, Frequency Domain. Frequency dependence of delay line coefficient S21 was obtained. Sizes of the microstrip and the gap between the strip and the ground ...

As the importance of nanoparticles is growing more and more, controlling and understanding the properties of nanoparticles became a focus of research. In this field Meyer at al.  are researching the GMR effect in granular gels to develop magnetoresistive sensors. The GMR in granular gels is simulated to investigate the physical processes in those systems. As soon as the models coincide with ...

A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...

Introduction Self-heating behaviour of dust accumulations is a multiphysics field coupled heat and mass transfer in the porous media. A typical experimental apparatus with a hot storage oven and mesh wire baskets has been taken as the study object. The influence of gas flow velocity, oxygen concentration and ambient temperature on the self-heating behaviour of the dry coal dust sample has been ...

In order to achieve an optimized design of the Multi-Lumen Thoracic Catheter (MLTC), fluid dynamics analyses were conducted utilizing COMSOL Multiphysics® software with LiveLink™ for Solidworks®. Lumen placement, diameters, and termination points were adjusted to ensure maximum drainage efficacy. It was determined through this study that even with the additional flow through the access lumen, ...

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of the bricks, in particular the predicted time at which brick shrinkage reverses into expansion, generating large ...
