    Theoretical and Experimental Analysis of Interfacial Instabilities in Multi-layer Flows for Different Polymer Melts

  • Original language description

    Modified Leonov model has been employed in the modelling of the coextrusion flows with same as well as different 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 modelling of the merging area with different polymer materials.

    Teoretická a experimentální analýza meziplošných nestabilit při vícevrstevném vytlačování odlišných polymerních tavenin

  • Czech description

    Byla provedena teoretická FEM analýza procesu vytlačování dvou odlišných polymerních tavenin a bylo zjištěno, že je nezbytně nutné použít adaptivní (nikoliv statické) konečně prvkové mřížky.
