Design of an intake and a thruster for an atmosphere-breathing electric propulsion system

Francesco Romano, Thomas Binderup Jensen

Challenging space missions include those at very low altitudes, where the atmosphere is the source of aerodynamic drag on the spacecraft, that finally defines the mission's lifetime, unless a way to compensate for it is provided. This environment is named ...

Observation of Alfvén Eigenmodes driven by off-axis neutral beam injection in the TCV tokamak

Olivier Sauter, Basil Duval, Duccio Testa, Alexander Karpushov, Marcelo Baquero Ruiz, Matteo Vallar, Claudio Marini, Filippo Bagnato, Lorenzo Stipani

Fast-particle driven Alfv´en Eigenmodes have been observed in low-collisionality discharges with off-axis neutral beam injection (NBI), electron cyclotron resonance heating (ECRH) and a reduced toroidal magnetic field. During NBI and ECRH, toroidicity indu ...

Mixed hydrogen-deuterium plasmas on JET ILW

Henri Weisen, Mikhail Maslov

A study of mixed hydrogen-deuterium H-mode plasmas has been carried out in JET-ILW to strengthen the physics basis for extrapolations to JET D-T operation and to support the development of strategies for isotope ratio control in future experiments. Variati ...

Computational modelling of fine sediment release using SEDMIX device with thrusters

Giovanni De Cesare, Azin Amini, Arianna Yadira Onate Paladines

Problem: Reservoir sedimentation occurs in dams worldwide, reducing the live storage available in the reservoirs. Possible solution: Jenzer-Althaus 2011) testes a water stirring device (called SEDMIX) that keeps sediments in suspension, enhancing its relea ...

Dynamic modelling of local fuel inventory and desorption in the whole tokamak vacuum vessel for auto-consistent plasma-wall interaction simulations

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Alessandro Pau, Cristian Sommariva, Henri Weisen, Richard Pitts, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Nicola Vianello, Mikhail Maslov, Federico Nespoli, Yao Zhou, David Pfefferlé, Davide Galassi, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Hamish William Patten, Samuel Lanthaler, Eric Serre, Bernhard Sieglin, Otto Asunta

An extension of the SolEdge2D-EIRENE code package, named D-WEE, has been developed to add the dynamics of thermal desorption of hydrogen isotopes from the surface of plasma facing materials. To achieve this purpose, D-WEE models hydrogen isotopes implantat ...

Integrated modelling of H-mode pedestal and confinement in JET-ILW

A pedestal prediction model Europed is built on the existing EPED1 model by coupling it with core transport simulation using a Bohm-gyroBohm transport model to self-consistently predict JET-ILW power scan for hybrid plasmas that display weaker power degrad ...

Plasma Diagnostics and Modelling of Nanosecond Pulsed Surface Dielectric Barrier Discharge Actuators

Sami Goekce

During the past years, an increasing number of studies have been conducted on the use of electrical discharges for the stabilization of airflows (plasma flow control). Electrical gas discharges transfer energy and momentum to the gas through collisions of ...
