  3. 3. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids

    Author : Naser Hamedi; Strömningsteknik; []
    Keywords : Non-Newtonian fluids; Correction factor; Fluid properties; Couette Rheometer; Particle interaction; Sedimentation; Computational Fluid dynamics; Plug flow; Herschel Bulkley; Power-law fluid; Immeresed boundary method;

    Abstract : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. READ MORE

  4. 4. Water in molecular outflows and shocks: Studies with Odin and Herschel

    Author : Per Bjerkeli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Herbig-Haro objects – ISM:individual objects: HH 54; outflows; VLA 1623 – ISM:jets and outflows – ISM:molecules – ISM:abundances – ISM:supernova remnants – stars:formation – stars:pre-main-sequence – stars:winds;

    Abstract : This thesis describes observations and analyses of water in molecular outflows from young stellar objects. The abundance of this molecule (with respect to molecular hy- drogen) is deduced from observations carried out with primarily the Odin and Herschel telescopes. READ MORE
