Mask to identify polluted periods during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Aerosol and trace gas measurements are strongly affected by the ship exhaust and other human activities (e.g., helicopter flights). Therefore, it is important to discriminate between clean and polluted periods. This mask provides an indication of clean per ...

Evaluation of feasibility and costs of alternative magnetic divertor configurations for DEMO

Holger Reimerdes

The European roadmap to the realisation of fusion energy has identified a number of technological and scientific challenges towards the development of a DEMO reactor. Mission 2 'Heat-exhaust systems' includes the investigation of alternative divertor confi ...

Unraveling the complexity of oxygen reactions on Pt surfaces

Rainer Beck, Ana Gutiérrez González

Platinum (Pt) is a key material in automotive catalytic converters used to clean up the exhaust of the combustion engine. Pt particles in a ceramic matrix serve as an oxidation catalyst to eliminate toxic carbon monoxide (CO) and unburned hydrocarbons (CxH ...

Two-phase and oil-free co-rotating scroll compressor/expander

Jürg Alexander Schiffmann

This paper discusses experimental and theoretical investigations about a re-designed co-rotation scroll machine, operating in compressor and expander mode. The machine has been tested under various operational conditions, with the aim to determine the infl ...

Evolution of nitrogen concentration and ammonia production in N-2-seeded H-mode discharges at ASDEX Upgrade

Olivier Sauter, Basil Duval, Richard Pitts, Timothy Goodman, Stefano Coda, Yann Camenen, Marco Wischmeier, Nicola Vianello, Federico Alberto Alfredo Felici, Cristian Sommariva, Laurie Porte, Alberto Bottino, Emiliano Fable, Antoine Pierre Emmanuel Alexis Merle, Andrea Scarabosio, Doohyun Kim, Haomin Sun, Dávid Wágner, Thomas Binderup Jensen

Ammonia formation was studied in a series of dedicated nitrogen seeded H-mode discharges at ASDEX Upgrade. The evolution of ammonia formation was investigated with a reference phase before the seeding, and a long, stable flat-top nitrogen-seeded phase. It ...

Carbon Dioxide Capture From Internal Combustion Engine Exhaust Using Temperature Swing Adsorption

François Maréchal, Shivom Sharma

In order to reduce the CO2 emissions in the transportation sector, one can electrify the vehicle, switch to biofuel, or capture and store CO2 on board. In this study, integration of an on board CO2 capture and storage unit with an internal combustion engin ...

Experimental implementation of a real-time power flux estimator for the ITER first wall on the TCV tokamak

Stefano Coda, Richard Pitts, Federico Nespoli, Benoît Labit, Cristian Galperti, Himank Anand

A control-oriented approach to the monitoring of wall power flux densities on ITER has been successfully developed. It is based on real-time equilibrium reconstruction in 2-D which is then used to describe the deposited heat flux as a poloidal flux functio ...

Engineering and integration risks arising from advanced magnetic divertor configurations

Holger Reimerdes

The divertor configuration defines the power exhaust capabilities of DEMO as one of the major key design parameters and sets a number of requirements on the tokamak layout, including port sizes, poloidal field coil positions, and size of toroidal field coi ...

Conduction-based model of the Scrape-Off Layer power sharing between inner and outer divertor in diverted low-density tokamak plasmas

Basil Duval, Marco Wischmeier, Benoît Labit, Nicola Vianello, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers, Roberto Maurizio, Hugo De Oliveira, Mirko Wensing

A simple analytic model for the repartition of the Scrape-Off Layer (SOL) exhaust power between the inner and outer divertors in a diverted low-density tokamak plasma is introduced. Electron heat conduction is assumed to dominate the heat transport, from t ...
