    Mathematical analysis of screw design modification increasing production rate during foam extrusion

  • Original language description

    In the presented study, the influence of screw design on temperature profile of processed material has been predicted by using the ANSYS Academic Research Polyflow package. The aim of the screw design modification has been to increase flow rate of the material by increasing the screw speed while achieving the temperature profile as in the case of standard screw, which leads to increase of the output of foam products. Modification of the screw design is based on defined pitch angle and defined shape, number and location of holes in the flight of the screw, as described in the literature [Fogarthy J. US Patent 6,015,227, Jan. 18, 2000]. Flow domain has been modeled in a rotating coordinate system (rotating cylinder and stationary screw) using the Mesh Superposition Technique and considering non-isothermal processing conditions and non-Newtonian behavior of the polymer melt described by the Carreau-Yasuda model. The defined FEM analysis successfully contributed to increase of the mass flow rate through the modified flow domain, which opens up the possibilities for future simulations of this issue.
