  1. 16. Computational study of rivulets using Volume of Fluid

    Författare :Tobias Tivert; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on numerical methods of soiling and some multiphase concepts related to it.The Volume of Fluid method was tested in two different test cases and showed fairly good results.The first test case was a gravity driven rivulet on an inclined plate, where it was an inlet with a constant water velocity at the beginning of the plate.

  3. 17. Stability analysis and control design of spatially developing flows

    Författare :Shervin Bagheri; Dan Henningson; Martin Berggren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global modes; transient growth; model reduction; feedback control; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Methods in hydrodynamic stability, systems and control theory are applied to spatially developing flows, where the flow is not required to vary slowly in the streamwise direction. A substantial part of the thesis presents a theoretical framework for the stability analysis, input-output behavior, model reduction and control design for fluid dynamical systems using examples on the linear complex Ginzburg-Landau equation.

  4. 18. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners

    Författare :Hans-Olof Backlund; FSCN - Fibre Science and Communication Network; []
    Nyckelord :Shear force; Tangential force; Temperature profile; Thermomechanical pulping;

    Sammanfattning : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. LÄS MER

  5. 19. Growth and Characterization of ZnO Nanocrystals

    Författare :Leif KE Ericsson; Kjell O Magnusson; Lars SO Johansson; Hanmin M Zhang; Omer Nour; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

    Sammanfattning : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. LÄS MER

  7. 20. A new experimental setup for studies on wake flow instability and its control

    Författare :Bengt Fallenius; Jens Fransson; Henrik Alfredsson; Christoffer Norberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning :  A new experimental setup for studies on wake flow instability and its control, which has been designed and manufactured, is introduced and described. The main body is a dual-sided flat plate with an elliptic leading edge and a blunt trailing edge. LÄS MER
