The control of the flux within continuous casting systems used in the metallurgical field can be obtained through the application of electromagnetic. The model here has been solved through a linear time-harmonic solver. The results of the electromagnetic model have then been applied to the fluid-mechanics model through volume Lorentz forces.

The Magnetic Refrigerator (MR) is a special type of refrigerator with potential to reduce the energy consumption of household refrigeration by a factor of two or more. To conduct numerical analysis of an experimental MR, a mathematical model was developed. The model solves the coupled Navier-Stokes and heat transfer equations which describe the physical phenomenon occurring within the MR. To ...

In this presentation we present our analysis of the PARC Nanocalorimeter. Calorimetry is basically the measuring of heat of chemical reactions or physical changes. Nanocalorimetry is Calorimetry at the Nanometer scale. The PARC Nanocalorimeter is a special type of Calorimeter, it consists of arrays of Nanocalorimeters. The PARC Nanocalorimeter is intended to be used for screening biochemical ...

Since the nineties many works have been dedicated to splat formation modeling. The main part of these works takes into account the molten droplet impact onto a flat surface, its flattening and solidification.The aim of this work is to test if a simplified model in 2D allows to characterize the real contact between the splat and the substrate and to compare the results of the experiments and the ...

An eigenvalue as well as a harmonic response analysis is performed on the Gullfaks C, Knock Out Drum (KOD) including some of the connecting pipe systems. The vibration behavior of two new choke valves and their specific connection to the KOD are of special interest. The main concern is the low frequency induced vibration as a consequence of the platform movements. A frequency band between 0-20 Hz ...

When the dimensions of the material approach is a comparable size to the phonon mean free path, heat flow enters a new regime, the nanoscale. The Fourier and Cattaneo Equations describe bulk heat flow well, but radiative boundary terms must be considered when modeling nanoscale heat flow. We take these equations and input them into COMSOL with the hope of eventually linking nanoscale and bulk ...

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux terms for the magnetic and gravitational force is used. Furthermore, experiments are carried out to verify the ...

Electrochemical Machining with a closed electrolytic free jet is a special procedure to generate complex micro structures by help of anodic dissolution. The work piece shape is fabricated by supplying an electrolytic current through an electrolyte jet ejected from a small nozzle. In this study COMSOL Multiphysics is used to simulate the electric current density in the jet and the dissolution ...

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 ...
