Numerical simulation can be advantageously employed to predict the main cell features (e.g., the reaction rate distribution on the electrodes, the cell voltage, or the electrolyte temperature) in order to optimize the design and operational conditions of the process. In this poster, we describe two complementary computational approaches applied to a molten salt electro-refiner for ...
Numerical Analysis for Surface Discharge on Solid Insulation in the Dielectric Liquid with Experimental Validation

Surface discharge initiation and propagation on the surface of an insulating solid immersed in a dielectric liquid were examined numerically and experimentally. To establish a generalized numerical technique for evaluating surface discharge phenomena using the electrohydrodynamics (EHD) approach, we employed the governing equations of EHD, including the Navier–Stokes equations. To these coupled ...

Nanoantennas – nanometer sized gold structures resonant at optical wavelengths have interesting properties for many applications. For numerical simulations of such structures simplified geometries are usually considered. However the fabricated shapes still differ significantly from perfect geometries and such structures are sensitive to geometrical changes. Here, we investigate how the deviation ...

After previous microwave simulations done with very hard assumptions, we improve the model by using Funer model to improve prediction of plasma effects on the microwave coupling. Some parameters are still not well known and are used as adaptation parameters. An experience plan technique is used to find these parameters by comparison of experimental measurements of reflected power to simulated ...

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular tissue receptors allowing one to focus on the imaging of the diseased tissue. In most cases Monte Carlo ...

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.

This paper will discuss the comprehensive solution adopted for converting the 3D digital/medical images directly into the computational model. The workflow using Simpleware Software – ScanIP and + ScanFE – will be illustrated including the option for directly exporting fully compatible models to COMSOL Multiphysics. The extra functionality that allows introduction, positioning and ...

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 actuation system of the deformable mirror is one of the crucial components of an Adaptive Optics unit. One possible implementation comprehends a linear force motor and a capacitive sensor providing the feedback measure signal. Choosing a magnetic circuit that makes optimum use of the magnetic force delivered by a current and properly arranging the electrostatic geometry allows to obtain very ...
