Numerical modelling of Bi-2223 multifilamentary tapes with position-dependent Jc

Francesco Grilli, Bertrand Dutoit

Different measurement techniques have demonstrated that due to better alignment during the manufacturing process, the central filaments in multifilamentary Bi-2223 tapes have higher critical current density than the outer filaments. A numerical model of no ...

Experimental and Numerical Analysis or Free Surface Flows in a Rotating Bucket

François Avellan, Sonia Kvicinsky

The aim of this study was to provide a complete experimental and numerical analysis of the flow in a rotating Pelton bucket. For the experimental analysis, several functioning points have been used in order to study differences which may occur in various s ...

Numerical modeling in induction heating for axisymmetric geometries

Jacques Rappaz, Rémy Glardon, Daniele Mari

This paper deals with numerical simulation of induction heating for axisymmetric geometries. A mathematical model is presented, together with a numerical scheme based on the Finite Element Method. A numerical simulation code was implemented using the model ...

Optimized Design on Variable-Speed Drives Based on Numerical Simulation.

Jean-Jacques Simond, Basile Kawkabani, Mai Tu Xuan, Alain Sapin

The proposed paper describes the modelling and the prediction of the steady- state or transient behaviour of different modern variable-speed drives. The necessity of a performant numerical simulation tool in order to guarantee an optimized design is illust ...

Modified FxLMS algorithms with improved convergence performance

Ali H. Sayed

This paper proposes two modifications of the FxLMS algorithm with improved convergence behaviour albeit at the same computational cost of 2M operations per time step as the original FxLMS update. The paper further introduces a generalized FxLMS recursion a ...

Numerical Modeling of Induction-Heating of Long Workpieces

Jacques Rappaz, Rémy Glardon

We consider in this paper an induction heating process. A mathematical model is presented, together with numerical methods used in order to describe the magnetic field, as well as the temperature field evolution. Experimental measurements were performed in ...

Numerical Modeling of Induction-Heating for 2-Dimensional Geometries

Jacques Rappaz

We present both a mathematical model and a numerical method for simulating induction heating processes. The geometry of the conductors is cylindrical and the magnetic field is assumed to be parallel to the invariance axis. The model equations have current ...

Numerical analysis of the precursor effect

David Andrew Barry

The precursor effect occurs when a dilute influent solution displaces a high-concentration resident solution. Some of the influent material is transported with the resident solution and appears around 1 pore volume in the breakthrough curve. A numerical so ...

Numerical analysis of the snow-plow effect

David Andrew Barry

A mathematical model describing the snow-plow effect, i.e. the removal of adsorbed ions from soil particles by an incoming solution with relatively high solute concentration, is analyzed. It is shown that an accurate numerical solution to the model must be ...
