1. 1. Numerical study of dynamics of mass-emitting particles in multi-phase flow

   Författare :Zeinab Moradi Nour; Minh Do-Quang; Fredrik Lundell; Gustav Amberg; Hans Kuipers; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles with outflow; lattice Boltzmann method; particle interaction; liquid-gas-solid systems; sedimentation; shear flow; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Suspended particles can be found in wide range of industrial applications such as food industry, mining industry and energy conversion processes. Depending on flow cases which particles are involved, different dynamics and motions are expected from suspended particles. LÄS MER

3. 2. How does O+ outflow vary with solar wind conditions?

   Författare :Audrey Schillings; Hans Nilsson; Rikard Slapak; Lars-Göran Westerberg; Christopher Cully; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric science;

   Sammanfattning : The entire solar system including Earth is enveloped in a region of space where the Sun’s magnetic field dominates, this region is called the heliosphere. Due to this position in the heliosphere, a strong coupling exists between the Sun and our planet. LÄS MER

4. 3. O+ outflow during geomagnetic storms observed by Cluster satellites

   Författare :Audrey Schillings; Hans Nilsson; Stephan Buchert; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmosfärsvetenskap; Atmospheric Science;

   Sammanfattning : The region of space dominated by the Sun's magnetic field is called the heliosphere. It envelops the entire solar system including Earth. Therefore, a strong coupling exists between the Sun and our planet. LÄS MER

5. 4. Numerical Vlasov–Maxwell Modelling of Space Plasma

   Författare :Bengt Eliasson; Bertil Gustafsson; Bo Thidé; Anders Bondeson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vlasov equation; Maxwell equation; Fourier method; outflow boundary; domain decomposition; Numerical Analysis; Numerisk analys;

   Sammanfattning : The Vlasov equation describes the evolution of the distribution function of particles in phase space (x,v), where the particles interact with long-range forces, but where shortrange "collisional" forces are neglected. A space plasma consists of low-mass electrically charged particles, and therefore the most important long-range forces acting in the plasma are the Lorentz forces created by electromagnetic fields.

7. 5. A Computational Investigation of Transport Phenomena in Stirred Reactors and Catalyst Particles

   Författare :Martin Lundén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Transport phenomena in stirred vessels and catalyst particles have been studied with computational models. The turbulent flow in a cylindrical, baffled vessel stirred with a coaxially mounted Rushton turbine was represented with a numerical solution of the transport equations. The influence of turbulence was accounted for by the .kappa. LÄS MER
