The approach of this project is Modeling a Coriolis Mass Flow-meter (CMF) bases on a Fluid-Structure Interaction (FSI) device. The "Coriolis mass flow-meter sensor" is modeled using COMSOL Multiphisics® simulation, the Acoustic-Shell Interaction physics interface and coupled by FSI physics interface to drive and simulate the sensor. The modeling and simulation are provided into two different ...

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good margin against electrical breakdown. By using a three-dimensional electromagnetic model of the entire power ...

The ceramic metal halide lamps belong to the most efficient high intensity light sources of these days. Presently it is the nitrogen contamination that causes the most significant problems during ignition. If this material gets into the lamp's interior in high concentrations, it will make the lamp unable to ignite properly at lower voltages. A self-consistent fluid model was developed in ...

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is considered as a problem of a great importance. Nowadays, however, microwave technique for localized testing biological ...

Plasma technology has potential applications in a wide range of areas, such as microwave reflectors/absorbers, material processing, sterilization and chemical neutralization. The knowledge about the fluid behavior in such systems has a central role, since the stability of the flow in the region of the electrical arc is essential for the development of a well-behaved torch. In this work, a ...

Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing flow through the stenosis. To examine the interaction of these factors, we applied computational fluid ...

Preparative chromatography is an important separation method where the simulated moving bed (SMB) technology is an increasingly used separation process for binary mixtures. Several chromatographic columns are arranged in a ring where the feedings and drains are changed cyclically to maintain a continuous separation. For this reason, an adaptive controller is proposed to adjust the flow rates ...

Hunting Lodge St. Hubertus is one of the most prominent Dutch buildings from the early twentieth century. An extensive study of wind and wind-driven rain (WDR) was conducted to provide insight into the moisture load of the building facade, using measurements and CFD simulations. COMSOL Multiphysics was also used for modeling the moisture transport through the walls of the tower. The model ...

It was suggested long ago that a theoretical model of a near-cathode region in a DC glow discharge admits multiple steady-state solutions describing different modes of currrent transfer. Even the most simple self-consistent models should admit such multiple solutions. In the present work, these solutions have been calculated for the first time with COMSOL Multiphysics.

Excilamps are artificial Ultraviolet sources based on the emission of excimers or exciplexes. The latter are excited states of weakly bound rare gas or halide/rare gas atoms which emit a photon in the UV region when they dissociate. Dielectric Barrier Discharge (DBD) excilamps are promising UV sources for the future, provided the coupling between their power supply is optimized. The model ...
