1. An Experimental Study of Reynolds Stress Closures in Shear Free and Weakly Sheared Turbulence
Sammanfattning : The objective of this thesis work is to obtain data enabling evaluation of closure hypotheses used in the Reynolds stress transport (RST) equations. Special attention has been devoted to studies of flow fields with shear free and weakly sheared turbulence. LÄS MER
2. Orientation of fibres in suspensions flowing over a solid surface
Sammanfattning : The orientation of fibres suspended in a viscous fluid, flowing over a solid surface, has been studied experimentally. A shear layer was generated, by letting the suspension flow down an inclined plate. LÄS MER
3. Studies of Topological Superconductors via Defects
Sammanfattning : Defects from impurities, edges, junctions or domain walls have local detrimental effects on the superconducting state. Defects are also important in topological superconductors, and useful in studying the properties of the superconducting order parameter. LÄS MER
4. Experimental study of bubble dynamics and transport
Sammanfattning : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. LÄS MER
