Bi-Directional Hydrogen Isotopes Permeation through the First Wall of a Magnetic Fusion Power Reactor
Plasma-driven permeation (PDP) and gas-driven permeation (GDP) through a first wall candidate material F82H have been investigated using a laboratory-scale steady state plasma facility. Experiments indicate that GDP may take place in the opposite direction of PDP, which then results in an unwanted increase in edge plasma density. A hydrogen flow from the plasma side to the gas side has also bee...
متن کاملInfluence of Pressure-Driven Gas Permeation on the Quasi-Steady Burning of Porous Energetic Materials
A theoretical two-phase-flow analysis is developed to describe the quasi-steady propagation, across a pressure jump, of a multi-phase deflagration in confined porous energetic materials. The difference, or overpressure, between the upstream (unburned) and downstream (burned) gas pressure leads to a more complex structure than that which is obtained for an unconfined deflagration in which the pr...
متن کاملGas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane
In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...
متن کاملStorage of hydrogen in nanostructured carbon materials
Recent developments focusing on novel hydrogen storage media have helped to benchmark nanostructured carbon materials as one of the ongoing strategic research areas in science and technology. In particular, certain microporous carbon powders, carbon nanomaterials, and specifically carbon nanotubes stand to deliver unparalleled performance as the next generation of base materials for storing hyd...
متن کاملMolecular simulations of hydrogen andmethane permeation through poremouthmodified zeolite membranes
Membrane-based separations are an attractive means to separate hydrogen from gas mixtures in order to use hydrogen in energy-related applications. Zeolite membranes are robust materials that are well suited to be used in harsh conditions, but they are not typically selective for hydrogen. Several studies have shown that highly selective separations of hydrogen are possible using zeolite membran...
