The purpose of this study was the optimization of an industrial furnace from a thermal point of view. Such a cylindrical furnace contains an Al-Mg molten alloy covered by a KCl-NaCl molten salt layer floating on it to prevent alloy evaporation. When tilting the cylindrical furnace, it was necessary to compute the relation between the salt and alloy volumes and the area of the liquid alloy/salt ...

Partial melting occurs beneath mid-ocean ridges in Earth's mantle and the resulting liquid migrates to the surface to form a new oceanic crust. In this system, mass can be exchanged between the liquid and solid phases through melting and solidification and, at the high temperatures and pressures associated with the Earth's interior, the solid matrix deforms through the process of compaction, ...

Strain induced by local deformation of a flexible micrometer-sized semiconductor tube is quantified by modeling a ball pressing on the tube wall. By changing the pressing condition, we are able to change the strain state of the tube wall incorporating self-assembled quantum dots (QDs) in the wall. The QD emission energy is calculated in COMSOL® by solving the Schrödinger wave equation ...

Strained technology is being promoted as the best way to extend the performance of semiconductor transistors. An inhomogeneous layer deposited on top of a silicon device can induce a strong modification in the real silicon strain state, and consequently in its electronic performance. Coupling the finite elements analysis done by COMSOL with a recursive CBED and LACBED dynamical simulation, we are ...

The steady-state non-equilibrium distributions of two species of mono-valent ions around a charged nanofluidic channel have been examined. Large reservoirs were placed on either side of the nanoscale channel to simulate bulk concentration of ions in a fluid. Results from COMSOL Multiphysics simulations show that the effect of the potential bias across the nanochannel yields a significant ...

The performance of simplified cylindrical cloaks with various material parameters was investigated. The performance metric was the overall scattering width of the cloak with various objects in the hidden region. COMSOL was used to simulate three cloaks with different material parameters to determine the total field in the simulation domain. For all cloaks simulated in this effort, a PEC-lined ...

Due to the complexity of electromagnetic modeling, researchers and scientists always look for development of accurate and fast methods to extract the parameters of electronic interconnects and package structures. In this paper, we illustrate modeling of multiconductor interconnects in multilayered dielectric media using COMSOL Multiphysics and the finite element method. We specifically determine ...

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into three subdomains. The rise of the waterfront is also simulated and the air overpressure thereby developed at the ...

Enzymatic biofuel cells (EBFCs) are miniature, implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study using COMSOL Multiphysics, we use an EBFC chip, having three dimensional, highly dense micro-electrode arrays, fabricated by C-MEMS micro-fabrication techniques. Glucose oxidase (GOx) is immobilized on anodes for ...
