  1. 6. Theoretical magnetohydrodynamic and solidification studies of continuous strip casting

    Författare :Hans B. Löfgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The continuous casting of steel strips has been under investigation and development for several decades. The aim of this development is to be able to cast steel strips in a thickness range from 1 to 10 mm. Today, there are basically two such methods: the single-belt caster and the twin-roll caster.

  3. 7. Computational Studies of Magnetohydrodynamic Stability for Reversed-Field Pinches and Tokamaks

    Författare :Donghui Liu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This work describes the ideal & resistive Magnetohydrodynamic (MHD) stability properties of Tokamak and Reversed-Field Pinch (RFP) plasmas. The first four papers are concerned with the cylindrical approximation of RFPs and tokamaks whereas the final two papers deal with a fully toroidal description. LÄS MER

  5. 9. Closed-loop control and identification of resistive shell magnetohydrodynamics for the reversed-field pinch

    Författare :Erik Olofsson; Per Brunsell; Wolfgang Suttrop; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasma physics with fusion; Plasmafysik med fusion; Automatic control; Reglerteknik;

    Sammanfattning : It is demonstrated that control software updates for the magnetic confinement fusion experiment EXTRAP T2R can enable novel studies of plasma physics. Specifically, it is shown that the boundary radial magnetic field in T2R can be maintained at finite levels by feedback. LÄS MER

  7. 10. Model predictive control of resistive wall modes in the reversed-field pinch

    Författare :Agung Chris Setiadi; Per Brunsell; Lorenzo Frassinetti; Cristian Rojas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The reversed-field pinch (RFP) is a magnetic confinement fusion (MCF) device. It exhibits a variety of unstable modes that can be explained by magnetohydrodynamic (MHD) theory. A particular unstable mode that is treated in this work is the resistive wall mode (RWM), which occurs when the shell of the device has finite conductivity. LÄS MER
