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.

It has become common place to use micro-electromechanical systems (MEMS) to evaluate the chemical properties of solutions. However, such microchips have not yet been applied to the analysis of radioactive solutions, for the purpose of nuclear safeguards, in the nuclear reprocessing industry. Implementing MEMS in this area results in a reduced volume of the sample to be analysed. This has many ...

Virtual prototyping is used for understanding, verifying, planning, controliing, and optimizing a technical application. It the industrial component computational science and engineering and can be called "the third pillar of modern science". The future of virtual prototyping will be multiscale and multiphysics models and simulations. --------------------------------- Keynote speaker's ...

Sensing electrodes array model of 3-Dimensional ERT/ ECT dual modality is established by using the software COMSOL. According to the uniformity of sensitivity field distribution, the correlation coefficient and the reconstructed image space resolution, the ECT/ERT dual modality sensing electrode arrays are optimized. Experimental results show that the optimized sensing electrode array of the ...

Partial differential equations which exhibit solutions that are spatial temporal patterns are often found in biological and chemical systems, e.g. when describing pattern formation in reaction-diffusion systems.Special classes of such patterns are relative equilibria and relative periodic orbits, which are solutions that in an appropriately co-moving frame of reference are stationary and ...

A microfluidic device for performing multiplexed cell bioassays has been successfully developed. The device takes advantage of laminar flow and hydrodynamic focusing in order to selectively load cells into various culture chambers and address cells with pharmacological agents. Both computational fluid dynamics (CFD) simulations and fluorescence microscopy illustrate how fluid flow can be ...

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 ...

This paper describes the automatic optimization of an electromagnetic actuator using a genetic algorithm. The actuator modeled here is dedicated for charge changing valve actuation in internal combustion engines. In the first step of the simulation, several operating points are calculated using the script language of COMSOL Multiphysics. In order to reduce computation time, only one segment of ...
