  1. 6. Suspensions of finite-size rigid particles in laminar and turbulent flows

    Författare :Walter Fornari; Luca Brandt; Jérémie Bec; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspensions; complex fluids; sedimentation; rheology; turbulence;

    Sammanfattning : Dispersed multiphase flows occur in many biological, engineering and geophysical applications. Understanding the behavior of suspensions is a difficult task. In the present work, we numerically study the behavior of suspensions of finite-size rigid particles in different flows. LÄS MER

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

    Författare :Naser Hamedi; Strömningsteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 9. Process Design for Ultrafiltration of Complex Process Streams

    Författare :Anna-Karin Nordin; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bleach plant effluent; Ultrafiltration; process design; optimization;

    Sammanfattning : Considerable effort has been dedicated over the years to model and simulate the ultrafiltration process. Most approaches are theoretical and therefore not applicable to industrial process streams. When treating such solutions, a combination of experiments and simulations is needed. LÄS MER

  7. 10. Statistical tools for ultrasonic analysis of dispersive fluids

    Författare :Jesper Martinsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis focuses on the possibility of using ultrasonic measurement techniques for energy gas characterization. The idea is to combine both on-line flow measurements with non-invasive fluid characterization in the same measurement setup using the same sensor(s). LÄS MER
