Title: More of the old and on with the new
Two experimental indicators from Shell for future energy computational research

Speaker: Mike Golombok (Shell, TU/e-ME)
Time: Nov 21, 2019, 10:00–11:00
Location: Differ, Alexander-zaal

Abstract
Numerical work normally models hypotheses and makes predictions which can be experimentally tested. In this seminar I will present two Shell projects where experimental observations suggest industrial potential and where computational modelling would help focus these observations on practical implementation for issues such as scale-up and process control. These examples are taken from the ‘old’ hydrocarbon and ‘new’ energy transition worlds.

Old world: Mobilising heavy oils
I will discuss the use of near critical water to crack and reduce viscosity of both ‘old’ bituminous oils and ‘young’ not yet ‘cooked’ oils. I will describe how modelling here will greatly reduce the requirement for unwieldy experimentation.

New world: Metal powders
These represent a new dense energy candidate for addressing problems of intermittency and storage when using renewable energy. Their implementation in existing infrastructure however, requires considerable reverse engineering of properties of a fuel which are completely unknown for the purposes of extended continuous burning.

Mike Golombok comes from Scotland. He has a BSc from University of Glasgow and a PhD from University of Toronto. He joined Shell in 1985. He did 15 years in refining and chemicals, 18 years in exploration and production and is currently in New Energy. Since 2006 he is a part-time professor at TU Eindhoven in mechanical engineering.

The CCER seminars are aimed at researchers interested in computational approaches to (energy) research. The seminar is small-scale, typically 15 participants, and interactive, offering lots of room for discussion.

Title: Modelling plasma and neutral gas dynamics in tokamak divertors and linear divertor simulators

Speaker: Egbert Westerhof (DIFFER)
Time: Nov 28, 2019, 10:00–11:00
Location: Differ, Alexander-zaal

Abstract
In any fusion energy reactor the hot plasma from the core of the reactor, where the fusion reactions occur, must be cooled down before it comes into contact with the reactor wall. In a magnetic confinement fusion reactor like a tokamak, the plasma flowing along the magnetic field lines outside the so-called ‘last-closed-flux-surface’ is diverted towards target plates well separated from the main plasma. Such a magnetic topology is called a divertor and allows to localize the plasma material interaction to a region where it can be controlled in order to prevent wall materials from entering the core plasma. In this presentation I will address the modelling of the plasma and neutral gas dynamics in tokamak divertors and in linear divertor simulators. I will present some of the main research and development issues that are being addressed for the design of a viable fusion energy reactor.
