1. 1. Modelling of the pressure distributions in twin-wire blade formers

   Författare :Claes Holmqvist; KTH; []
   Nyckelord :fluid mechanics; blade forming; pressure distribution; suction; interaction; permeable fabric; modules;

   Sammanfattning : During papermaking, the internal structure of the fibrenetwork constituting the paper is to a dominating extentdetermined in the forming zone of the paper machine. Thisthesis is aimed at studying the pressure distribution in bladeforming sections, which is commonly considered to be a keyquantity of the process. LÄS MER

3. 2. Mechanical modelling of blade forming and drainage of flocculated suspensions

   Författare :Claes Holmqvist; Anders Dahlkild; Douglas Bousfield; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; blade forming; pressure distribution; interaction; suction; drainage; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : A method has been developed for flexible modelling of multi-component twin-wire blade formers. Features such as suction devices, loadable blades, curved blades, and partial contact between the blades and the forming fabrics are easily incorporated. LÄS MER
