1. 16. Numerical Modeling of Turbulent Gas-Particle Flow

   Författare :Aldo Benavides; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence modulation.; kinetic theory; Eulerian-Eulerian model;

   Sammanfattning : This work presents a theoretical and numerical study of gas-particle two-phase flow within the Eulerian framework. Although gas-particle flows have been extensively studied, there is still no general agreement on the constitutive equations for an Eulerian-Eulerian model in which the dispersed phase is treated as a continuum, i.e. a granular fluid.

3. 17. Numerical Simulation as a Tool for Studying Waves and Radiation in Space

   Författare :Lars Kristen Selberg Daldorff; Bo Thide; Francesco Califano; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; space physics; plasma physics; kinetic plasma; plasma simulations; beam instabilities; Space physics; Rymdfysik;

   Sammanfattning : Plasma physics governs the area of interactions between charged particles. As 99% of the visible universe is in a plasma state, it is an important topic in astronomy and space physics, where we already at an altitude of 60 km reach the plasma environment surrounding our planet in the form of the ionosphere.

7. 20. Numerical modeling of pulsed volume discharges for the generation of ozone

   Författare :J. Olof Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modeling; ozone production; parameterstudy; pulsed discharge;

   Sammanfattning : The pulsed electric volume discharge is a new alternativefor the efficient generation of ozone in compact systems. Thisthesis presents a parameter study of the reactions in this kindof homogeneous discharge, using a here developed numericalmodel DISCHEM which solves plasma chemical kinetic rate andenergy equations.
