Abstract: | Flow visualisation studies are preformed to determine the effects of die geometry on interfacial instabilities in coextrusion flows of a LDPE melt. Slit coextrusion visualisation cells with 30° and 90° convergent stream angles are used in this study. Stream ratios leading to interfacial instability in the LDPE melt are quantified and compared for each geometry. |
