International audience; We present measurements of the sticking probability of ammonia on two metals, tungsten and 316L stainless steel, covered with natural surface impurities as they will be used for the international nuclear fusion experimental re

We performed a direct comparison of deuterium retention and release from tungsten in presence or in absence of oxygen impurities. A single crystal of W(110) was used to prepare tungsten with four different surface states: with its native oxide, atomi

International audience; This work focuses on the production of negative-ions on graphite and diamond surfaces bombarded by positive ions in a low pressure (2 Pa) low power (20 W) capacitively coupled deuterium plasma. A sample is placed opposite a ma

3-D Modeling of unsteady free-surface flow in open channel/ Modélisation tridimensionnelle d'un écoulement instationnaire à surface libre en riviére

Publikováno v: Journal of Hydraulic Research. 42:263-272

We present the hydrodynamic part of a three-dimensional model for pollutant dispersion in turbulent free-surface flow in open channels. It does not require any strong assumption such as hydrostatic pressure and is able to simulate an unsteady free-su
