Scrape-off layer simulations in a Double Null magnetic configuration

Paolo Ricci, Paola Paruta, Fabio Riva, Christoph Wersal, Carrie Fiona Beadle

Different magnetic geometries are being considered for handling the power exhaust in DEMO, among which is the double-null. In addition to doubling the exhaust area, experiments have found stark differences in the SOL on the HFS and LFS in this configuratio ...

Testing and modelling of a novel oil-free co-rotating scroll machine with water injection

Jürg Alexander Schiffmann, Luis Carlos Mendoza Toledo

Efficient compressed air energy storage requires reversible isothermal compression and expansion devices. The isothermal compression and expansion processes can either be approached by several stages with intercooling or by the more convenient injection of ...

Water-assisted oxygen activation during gold-catalyzed formic acid decomposition under SCR-relevant conditions

Davide Ferri, Oliver Kröcher

Owing to the problems associated with the use of urea as an ammonia precursor compound in the selective catalytic reduction process in automobiles, alternative compounds such as ammonium formate, methanamide, and guanidinium formate have been suggested as ...

The DTT device: Power and particle exhaust

Holger Reimerdes

The possible scenarios at full power of the DTT (Divertor Test Tokamak) device with the standard single null (SN) and X divertor (XD) configurations have been analysed for the aspect of safely handling the power to be exhausted on the divertor targets. In ...

Overview of ASDEX Upgrade results

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Federico Alberto Alfredo Felici, Cristian Sommariva, Laurie Porte, Antoine Pierre Emmanuel Alexis Merle, Haomin Sun, Yann Camenen, Marco Wischmeier, Nicola Vianello, Alberto Bottino, Emiliano Fable, Andrea Scarabosio, Doohyun Kim, Dávid Wágner, Thomas Binderup Jensen, Donghyun Kim, Xiao Wang, Bernhard Sieglin, Otto Asunta, Hartmut Zohm, Emanuele Poli, Gergely Papp, Giovanni Tardini

The ASDEX Upgrade (AUG) programme is directed towards physics input to critical elements of the ITER design and the preparation of ITER operation, as well as addressing physics issues for a future DEMO design. Since 2015, AUG is equipped with a new pair of ...

Plasma refuelling at the SOL simulated with the GBS code

Paolo Ricci, Paola Paruta, Fabio Riva, Christoph Wersal, Carrie Fiona Beadle, André Calado Coroado

The scrape-off layer (SOL) sets the bounday conditions of a tokamak, determining the plasma confinement, the heat exhaust, the impurity levels, and controlling the fuelling of the device. Therefore, a first principles understanding of the physical mechanis ...

The DTT device: Rationale for the choice of the parameters

Basil Duval, Holger Reimerdes

The main goal of the Divertor Tokamak Test facility (DTT) is to explore alternative power exhaust solutions for the next step after ITER, i.e., a demonstration power plant DEMO that will explore steady-state operation.The principal objective of DTT is to m ...

Modeling and Designing of a Radial Anode Off-Gas Recirculation Fan for Solid Oxide Fuel Cell Systems

Jan Van Herle, Jürg Alexander Schiffmann, Stefan Diethelm, Zacharie Wuillemin, Patrick Hubert Wagner

To improve the industry benchmark of solid oxide fuel cell (SOFC) systems, we consider anode off-gas recirculation (AOR) using a small-scale fan. Evolutionary algorithms compare different system design alternatives with hot or cold recirculation. The syste ...

A Drift-Kinetic Model for Tokamak SOL Plasmas

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

A fluid drift-reduced description, which accurately describes phenomena occurring on time scales slower than the characteristic gyro-frequencies and space scales longer than the Larmor radii, has been successfully used in recent years to model the dynamics ...
