Modeling of TAE mode excitation with an antenna in realistic X-point geometry

Ambrogio Fasoli, Duccio Testa

Experimentally, it is observed that Toroidal Alfven Eigenmodes (TAEs) are difficult to excite with an external antenna when the plasma is in X-point geometry. Here, the effect of the X-point geometry on the efficiency of the TAE excitation with the externa ...

AMER INST PHYSICS2020

Subsurface scattering, in which light refracts into a translucent material to interact with its interior, is the dominant mode of light transport in many types of organic materials. Accounting for this phenomenon is thus crucial for visual realism, but exp ...

ASSOC COMPUTING MACHINERY2019

Metal fasteners and adhesive bonding are the main assembly methods in modern timber constructions. However, traditional wood-wood connections can be used effectively as well, thanks to increasing automation of the construction industry (CNC, robotics, etc. ...

Flow boiling and frictional pressure gradients in plate heat exchangers. Part 1: Review and experimental database

John Richard Thome, Raffaele Luca Amalfi, Farzad Vakili Farahani

This two-part paper presents an overview of evaporation heat transfer mechanisms, a review of the experimental and prediction methods and a creation of a consolidated multi-lab database of 3601 data points and provides a detailed comparison of all the pred ...

Simulation of viscoelastic fluids in a 2D abrupt contraction by spectral element method

Michel Deville, Nicolas Fietier, Azadeh Jafari

This study presents the vortex structure and numerical instability increase occurring when the level of elasticity is enhanced in inertial flows in planar contraction configuration for finitely extensible nonlinear elastic model by Peterlin (FENE-P) fluid ...

Study of the vortex-induced pressure excitation source in a Francis turbine draft tube by particle image velocimetry

François Avellan, Arthur Tristan Favrel, Christian Landry, Keita Yamamoto

changes and loses its coherence, leading to a drastic reduction in the intensity of the induced excitation source. Francis turbines operating at part-load experience the development of a precessing cavitation vortex rope at the runner outlet, which acts as ...

CFSPro: Ray Tracing for Profile Optimisation of Complex Fenestration Systems using mixed dimensionality approach

Andreas Schueler, André Gabriel Kostro

An advanced optical ray tracing software was developed for the extensive study of Complex Fenestration Systems. Using an algorithm mixing two and three-dimensional approaches, very fast and accurate computation of large number of rays in complex geometries ...

The demand for improved performances of power transmission devices requires ever smaller dimensions and higher working voltages which lead to increased risk of breakdown, for example, in satellite slip rings. Previous works are mostly limited to breakdown ...

Iop Publishing Ltd2013

When implementing high-order surface impedance boundary conditions in collocation boundary element method (BEM) with constant or linear elements, difficulties arise due to the computation of the curvature of the conductors and of the tangential derivatives ...

Parallel Molecular Dynamics with Irregular Domain Decomposition

The spatial domain of Molecular Dynamics simulations is usually a regular box that be easily divided in subdomains for parallel processing. Recent efforts aimed at simulating complex biological systems, like the blood flow inside arteries, require the exec ...
