  1. 16. Direct numerical simulation of turbulent flow in plane and cylindrical geometries

    Författare :Jukka Komminaho; KTH; []
    Nyckelord :turbulence; plane Couette flow; pipe flow; laminar-turbulent transition; direct numerical simulation; spectral methods;

    Sammanfattning : This thesis deals with numerical simulation of turbulentflows in geometrically simple cases. Both plane and cylindricalgeometries are used. The simplicity of the geometry allows theuse of spectral methods which yield a very high accuracy usingrelatively few grid points. A spectral method for planegeometries is implemented on a parallel computer. LÄS MER

  3. 17. Investigations of In-Plane Properties of Paperboard

    Författare :Anton Hagman; Mikael Nygårds; Bo Westerlind; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In-plane properties of paperboard have always been of interest to paper mechanical researchers. The reason for this is that they play a large role for the usability of the paperboard throughout its lifespan.  Tensile properties are crucial when the board is fed through printing and converting machines at high speeds in the beginning of its life.
