  1. 16. IronArc a New Process for Pig Iron Production : A Numerical and Experimental Investigation Focusing on Mixing

    Författare :Kristofer Bölke; Mikael Ersson; Pär Jönsson; Stein Tore Johanssen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixing time; Penetration depth; CFD simulations; IronArc; Water modeling; Mixing time Experiments; Omrörningstid; Penetrationsdjup; CFD simuleringar; IronArc; Vattenmodellering; Omrörningsexperiment; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : I den här studien så var syftet att undersöka omrörningen och relaterade fenomen i den nyutvecklade IronArc processen. Processen använder sig av gasinjektion genom plasmageneratorer för att smälta och reducera en slagg bestående av järnoxid. LÄS MER

  3. 18. Concurrent Engineering of Small Satellites using Hardware-in-the-loop Simulations

    Författare :Cristóbal Nieto-Peroy; Mathias Milz; Élcio Jeronimo de Oliviera; Giovanni Palmerini; Sergio Montenegro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concurrent Engineering; Hardware-in-the-loop Simulation; Small Satellite; CubeSat; Nanosatellite; Test-driven Development; Behavior-driven Development; Frictionless Platform; Floating Platform; Onboard space systems; Rymdtekniska system;

    Sammanfattning : The miniaturization of spacecraft has brough the possibility of conducting space missions to a vast portion of private enterprises and scientific institutions. The inaccessibility of modest developers to the resources that governmental agencies and primary contractors utilize to develop conventional satellites has not been an obstacle for them to apply different, more agile and risk-seeking approaches.

  4. 19. Validating User Engagement and Effectiveness of Training Simulations : A mixed-methods approach informed by embodied cognition and psychophysiological measures

    Författare :Hiran B. Ekanayake; Robert Ramberg; Tom Ziemke; Per Backlund; Kamalanath Priyantha Hewagamage; Craig Lindley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; training simulators; simulation validation; psychological fidelity; psychophysiological measures; embodied cognition; electroencephalography EEG ; galvanic skin response GSR ; träningssimulatorer; validering av simuleringar; psykologisk realism; psyko-fysiologiska mått; kroppslig kognition; elektroencefalografi EEG ; galvanisk hudrespons GSR ; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Simulation-based training has gained widespread attention recently as a response to drawbacks associated with traditional training approaches, such as high training costs (instructors, equipment, etc.), high risks (e.g. pilot training), and ethical issues (e. LÄS MER

  5. 20. Turbulent flows over permissive boundaries and porous walls

    Författare :Seyed Morteza Habibi Khorasani; Shervin Bagheri; Geert Brethouwer; Alfredo Soldati; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulations; wall-bounded turbulence; flow control; porous walls; heat transfer; Direkta numeriska simuleringar; väggbunden turbulens; flödeskontroll; porösa väggar; värmeöverföring; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : This thesis investigates how in wall-bounded turbulent flows changes to the wall can induce changes in the flow. To this end, we investigate the use of wall boundary conditions meant to mimic the effect of textured surfaces. LÄS MER
