Radiofrequency Inductive Coupled Plasmas Towards Low Pressure

M. Cavenago
Laboratori Nazionali di Legnaro
INFN
Legnaro, Italy

Inductively coupled plasmas (ICP) are largely used as a convenient way to produce large ion currents in industrial applications and for particle accelerators and for the Neutral Beam Injectors (NBI) envisioned for tokamak heating (ITER project and beyond). Among specifications we have ... En savoir plus

Modeling Contact Line Dynamics in Evaporating Menisci

J. Plawsky[1], A. Chatterjee[1], and P.C. Wayner Jr.[1]
[1]Department of Chemical and Biological Engineering, Rensselaer Polytechnic Institute, Troy, New York, USA

The Constrained Vapor Bubble is a fundamental fluid mechanics experiment that is scheduled to run aboard the International Space Station starting in August 2009. The experiment is focused on looking at evaporation and condensation processes at the contact line, where vapor, liquid and ... En savoir plus
