    Abstract : I denna avhandling studeras elektromagnetisk vågutbredning i graderade materialkompositer med extraordinära egenskaper. Två sådana materialkompositsystem studeras särskilt, med hjälp av både analytiska och beräkningstekniska elektromagnetiska metoder. READ MORE

  4. 2. Simulations of the Dynamics of Fibre Suspension Flows

    Author : Stefan B Lindström; Tetsu Uesaka; Myat Htun; Fritz Bark; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre; fibre suspension; simulation; paper; papermaking; forming; fibre orientation distribution; fibre flexibility; viscosity; first normal stress difference; fluid flow; simple shear flow; two-way coupling; three-dimensional; Chemical engineering; Kemiteknik; Engineering physics; Teknisk fysik;

    Abstract : A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.
