  1. 1. Near wall fibre orientation in flowing suspensions

    Author : Allan Carlsson; Daniel Söderberg; Fredrik Lundell; Helge I. Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid mechanics; fibre orientation; shear flow; wall effect; fibre suspension; papermaking; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis deals with fibre orientation in wall-bounded shear flows. The primary application in mind is papermaking. The study is mainly experimental,but is complemented with theoretical considerations.The main part of the thesis concerns the orientation of slowly settlingfibres in a wall-bounded viscous shear flow.

  2. 2. A study on axially rotating pipe and swirling jet flows

    Author : Luca Facciolo; Herik Alfredsson; Helge I. Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Abstract : The present study is an experimental and numerical investigation on rotating flows. A special facility has been built in order to produce a turbulent swirling jet generated by a fully developed rotating pipe flow and a Direct Numerical Simulation (DNS) code has been used to support and to complement the experimental data.

  4. 4. Particle-laden Turbulent Wall-bounded Flows in Moderately Complex Geometries

    Author : Azad Noorani; Philipp Schlatter; Helge Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; complex geometry; particle; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wall-bounded turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the carrier and the particulate phase is elevated to a higher level when introducing geometrical complexities such as curved walls. READ MORE
