    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; droplets; suspension; multiphase flow; microfluidics; soft matter; rheology; depletion force; level set; ghost fluid.; droppar; suspension; flerfasflöde; mikrofluidik; mjukt material; reologi; utarmningskraft; nivåuppsättning; spökvätska.; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Micron to millimetre sized droplets, precisely generated or sustained in controlled environment, have great potential in myriads of engineering applications functioning as the basic element to assemble metamaterials, deliver drugs, host surfactant, reduce friction and damp turbulence. The interaction of droplets from pairwise to collective levels is the most important factor in controlling these processes, yet little is known about the detailed mechanisms in various nonideal conditions.

    Sammanfattning : The work presented in this dissertation was carried out at the Division ofMechanics, Department of Management and Engineering at Link¨oping University,between 2003 and 2008. It was supervised by Prof. LÄS MER

  4. 18. Particle-fluid interactions under heterogeneous reactions

    Författare :Thamali Rajika Jayawickrama; Kentaro Umeki; Nils Erland L. Haugen; Matthaus Babler; Muhammad Aqib Chishty; Henrik Ström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; drag coefficient; Nusselt number; Sherwood number; particle-fluid flow; reacting flow; Energy Engineering; Energiteknik;

    Sammanfattning : Particle-fluid flows are involved in many natural processes and industrial applications; some examples are drying, solid fuel combustion, gasification, and catalytic cracking. It is vital to understand the phenomena involved in particle-fluid flows in depth for design, predictions and process improvements. LÄS MER

  5. 19. Parallel computing of fluid flow through porous media

    Författare :Gunnar Hellström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Fluid flow through porous media takes place in a variety of technical areas including ground water flow, flow through embankment dams, paper making, composites manufacturing, filtering, drying and sintering of iron ore pellets. When modelling these kinds of flows it is common practice to use averaging techniques rather than computing the detailed flow field in every single pore. LÄS MER

  7. 20. Internal erosion in embankment dams : fluid flow through and deformation of porous media

    Författare :J. Gunnar I. Hellström; Thanasis D. Papathanasiou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. LÄS MER
