The overall goal of this work is the use of COMSOL Multiphysics® in the modeling of the current density distributions for the electrodeposition of aluminum coatings from ionic liquids. The local current distribution is strongly dependant on the conductivity and on the geometry of the galvanic cell and can only be computed by the numerical solution of the partial differential equations ...

The understanding of quench, or the sudden transition to the normal state of a high-current Superconductor (SC), is fundamental for the design of a SC magnet, and it is widely discussed in the literature. This paper presents some simple COMSOL models, which are compared with well-known approximate formulae and some experimental results. These models allow a more precise description than it is ...

This paper illustrates how to set up and solve a two-dimensional flow problem having dimensions of 640 x 320 micro-meter using the Navier-Stokes equations with the help of COMSOL Multiphysics solver. The principle of our pore-scale modeling approach is composed of two steps. The first step involves the detailed identification and specification of the porous medium morphology, this step was ...

Prototype Fast Breeder Reactor (PFBR) is a 500MWe, sodium cooled, pool type, mixed oxide (MOX) fuelled reactor. Sodium flow measurement in various loops of the reactor is of prime importance from the operational and safety aspects. To measure the flow of electrically conducting sodium in large secondary circuit pipes, probe type permanent magnet flowmeters (PTFM) are used. PTFM works on the ...

TAP (Temporary Analysis of Products) reactors are powerful instruments to study the kinetics of catalytic reactions. Their basic principle, exposition of evacuated solids of interest to narrow pulses containing very small amounts of gases, and measuring the concentrations of outgoing molecules permits to study practical catalysts under the conditions approaching those of molecular beam ...

Porous Silicon (PS) can easily be formed by electrochemical etching of silicon in HF based electrolytes at room temperature. Since, PS is compatible with silicon IC technology; it finds lot of applications in the fabrication of MEMS devices. In the current study, we discuss the design of a condenser microphone using a Silicon/ Porous Silicon composite membrane as a movable plate. The performance ...

In the frame of an ESA project, CSEM in collaboration with other partners has developed an innovative Attitude Orbit Control System concept that relies on a Reaction Sphere. We propose to use one unique magnetic bearing Reaction Sphere whose spin axis and angular velocity can be positioned by dedicated control. The design is based on a 3-D permanent magnet motor obtained with a multi pole rotor ...

Carbon Nanotubes (CNTs) have remarkable mechanical, thermal and electrical properties. The properties of CNTs depend on atomic arrangement (how the sheets of graphite are rolled), the diameter and length of the tubes and morphology of nanostructure. In this paper effective elastic properties of CNT based polymer composites are evaluated using a square Representative Volume Element (RVE) in ...
