  4. 2. Test Charge Response of a Dusty Plasma with Grain Size Distribution and Charging Dynamics

    Author : Muhammad Shafiq; Michael A. Raadu; Jens Juul Rasmussen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dusty plasmas; Complex plasmas; Grain size distribution; Grain charging dynamics; Lorentzian distribution; Kappa distribution; Test charge response; Delayed shielding; Energy loss; Drag force; Wake field.; Plasma physics; Plasmafysik;

    Abstract : This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. READ MORE

  5. 3. A study of micro-particles in the dust and melt at different stages of iron and steelmaking

    Author : Muhammad Nabeel; Andrey Karasev; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle size distribution; ironmaking; iron ore pellets; dust generation; mechanical wear; friction; reduction; REM clusters; Electrolytic extraction; cluster size distribution; growth mechanism; collisions; statistical analysis.; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The dust particles generated due to mechanical wear of iron ore pellets and clusters formed in molten stainless steel alloyed with rare earth metals (REM) are considered in this study. Firstly, the influence of the characteristics of iron ore pellets, applied load on a pellet bed and partial reduction of the pellets on the size distribution of the generated dust was investigated.

  7. 5. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function

    Author : Karl Netzell; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; flamelet model; Physics; particle distribution; soot; moment method; sectional method; particle size distribution function;

    Abstract : Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective.
