Comparison of TSMS and MQC models for (a) bubble radius and (b) axial derivative of bubble radius (dR/dZ). None of the profile plots in the manuscript go past as data were not available and nothing interesting happens beyond that point.

Image of FIG. 3.
FIG. 3.

Comparison of TSMS and MQC models with data for (a) temperature and (b) crystallinity.

Image of FIG. 4.
FIG. 4.

Spatial profiles for the components of the total stress tensor for the TSMS model: (a) flow direction with amorphous , semi-crystalline , and combined phases; (b) transverse direction with amorphous , semi-crystalline , and combined phases. Table III values, , and apply.

Image of FIG. 7.
FIG. 7.

Effect of TUR on spatial profiles of bubble-tube variables for the TSMS model: (a) bubble-tube radius, (b) temperature, (c) thickness reduction, and (d) crystallinity. Table III conditions apply and .
