    • 2D FSI model for paper webs and fabrics moving close to each other in complex geometries 

      Immonen, Eero; Bergstrom, Fredrik; Nurmi, Simo; Lehtinen, Antti; Juppi, Kari; Martinsson, Lars (Oklahoma State University, 2009-06)
      In the present article we develop a two-dimensional computational fluid-structure interaction (FSI) model for small transverse deflections of a moving paper web, supported on one side by a fabric, both moving in an arbitrary ...

    • Modeling grooved rolls with moving 2D porous media 

      Nurmi, Simo; Berstrom, Fredrik; Immonen, Eero; Lehtinen, Antti; Juppi, Kari; Martinsson, Lars (Oklahoma State University, 2009-06)
      Rolls are widely used in paper machines to heat, press and support paper webs and fabrics in order to facilitate rapid drying and transport of the paper web through the machine. In modern high speed paper machines, however, ...

    • Transient 2D paper web drying model based on CFD 

      Lehtinen, Antti; Bergstrom, Fredrik; Immonen, Eero; Nurmi, Simo; Martinsson, Lars; Ingvarsson, David; Juppi, Kari (Oklahoma State University, 2009-06)
      In the present article, a model combining the benefits of the small scale and large scale approaches towards modeling paper drying in a paper machine dryer section environment is described. The model is transient and ...
