RAMIREZ, Daniel; ESTRADA, Omar; LOPEZ, Iván  and  OSSWALD, Tim A. SIMULATION OF THE FOUNTAIN FLOW EFFECT USING MESHLESS METHODS. Rev. LatinAm. Metal. Mater. [online]. 2013, vol.33, n.2, pp.206-2013. ISSN 0255-6952.

The fountain flow effect affects the macromolecular orientation and therefore, the mechanical and optical properties of injection and compression molded parts [1]. The impact of the fountain flow effect is even higher in fiber reinforced materials, because the distribution and orientation of fibers is affected. The fountain flow effect is modeled using a meshless technique, the radial function method (RFM). Two cases are considered: a slit flow of a power law fluid and a vertical tube flow of a Newtonian fluid considering gravitational effects. A good agreement between the numerical prediction and results reported in literature was found

Keywords : Fountain flow effect; polymer injection moulding; meshless method; radial basis functions.
