Modeling of Viscoelastic Multi-layer Flows for Different Polymer Melts
Original language description
Modified Leonov model has been employed in the modeling of the coextrusion flows with same as well as differerent polymer melts. Flow visualization measurements were used for verification of the used numerical scheme. Specific attention is paid here to the possible numerical difficulties which may occur during modeling of the merging area with different polymer materials. Both, measurements as well as FEM analysis of the coextrusion flows were discussed from the wave type of interfacial instabilities point of view.

Modelování vícevrstevného toku vzájemně odlišných viskoelastických polymerních tavenin
Czech description
Byla provedena teoretická a experimentální analýza procesu koextruze pro dva odlišné polymerní systémy. Bylo zjištěno že pro dosažení přesného výpočtu napěťového pole v oblasti soutoku jednotlivých vrstev je nutno použít adaptivní (nikoliv statickou) konečně prvkovou mřížku.
