2. 1. A Novel Fiber Interaction Method for Simulation of Early Paper Forming

   Author : Gustav Kettil; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber suspension flow model; object-object interaction model; contact forces; lay down simulations; paper forming; immersed boundary methods; contact forces;

   Abstract : In the forming section of a paper machine, a fiber suspension is flowing down onto a forming fabric, and a paper structure is formed. By using computer simulations this process can be studied, attaining new knowledge helping to improve paper quality and machine efficiency. READ MORE
