  2. 1. Auroral electrodynamics of plasma boundary regions

    Author : Sónia Liléo; Göran Marklund; Anders Eriksson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Abstract : The electrodynamic coupling between the auroral ionosphere and the magnetosphere is the main subject of this thesis. Satellite measurements of electric and magnetic fields and of charged particles are used to explore three distinct plasma boundaries, magnetically linked to the nightside auroral ionosphere.

  4. 2. Development Towards Sustainable Ironmaking : The IronArc Process

    Author : Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. READ MORE

  5. 3. Thermodynamic Modelling and Performance of Combined Solid Oxide Fuel Cell and Gas Turbine Systems

    Author : Jens Pålsson; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; Gases; fluid dynamics; plasmas; plasma; hydraulik; Maskinteknik; vibration and acoustic engineering; hydraulics; vacuum technology; Modelling; Mechanical engineering; Solid oxide fuel cell; Hybrid system; Gaser; fluiddynamik;

    Abstract : Solid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. READ MORE

  6. 4. Fundamental aspects of HiPIMS under industrial conditions

    Author : Mattias Samuelsson; Ulf Helmersson; Torbjörn Joelsson; Hans Högberg; Bengt Wälivaara; Jörg Patscheider; Linköpings universitet; []
    Keywords : ;

    Abstract : Fundamental aspects of the high power impulse magnetron sputtering (HiPIMS) process and its implication for film growth under industrial conditions have been studied. The emerging HiPIMS technique exhibits a higher plasma density and an enhanced degree of ionisation of sputtered material as compared to conventional direct current magnetron sputtering (DCMS).

  7. 5. Investigation of Quark Gluon Plasma-like signals with Lund string interactions

    Author : Smita Chakraborty; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Heavy-ion collisions; QGP-like signals; Proton-proton collisions; Jets; Fysicumarkivet A:2022:Chakraborty;

    Abstract : This thesis investigates the interactions that occur in extreme densities for high-energy collisions of subatomic particles. The theoretical models developed for this purpose are based on the Lund model. The developments have been implemented as a new module called Gleipnir to the Monte-Carlo event generator, P YTHIA .
