  3. 3. Modeling nanofiber transport and deposition in human airways

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Sofie Högberg; Luleå tekniska universitet.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : An understanding of the complex motion of fibrous particles is important in a wide range of areas, including inhalation toxicology, targeted drug delivery, composites manufacturing, paper making, and food processing. While the applications are diverse, the governing equations for the fiber motion may be shared. LÄS MER

  4. 4. Permeability modelling and particle deposition mechanisms related to advanced composites manufacturing

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Markus Nordlund; Luleå tekniska universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Advanced composite materials reinforced by Non-Crimp Fabrics (NCFs) are becoming increasingly popular for high performance, light weight, complex structures, due to their high mechanical properties and relatively cheap production costs. These materials, not only improve the structural properties, but also induce great possibilities for reduced fuel consumptions for aircrafts and automotives, due to their high strength to weight ratio.

  5. 5. Eulerian Numerical Study of the Sedimentation of Fibre Suspensions

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Feng Zhang; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fokker-Planck equation; particle fluid flow; suspension; instability;

    Sammanfattning :  Sedimenting suspensions exist in a varity of natural phenomena and industrial applications. It is already observed in experiments that the dilute fibre suspensions experience a hydrodynamics instability under gravity at low Reynolds numbers. Initially well-mixed suspensions become inhomogeneous and anisotropic due to this instability. LÄS MER
