The following captions should read:
Fig. 2 Numerically predicted contour plots of temperature (at left in and stream function (right) for (a) case E1 and (b) case E2
Fig. 3 Axial variation of the predicted polymer temperature (at and the furnace wall temperature for cases E1 and E2
Fig. 4 Axial variation of the radiative and convective heat flux experienced at the polymer’s surface for case E1
Fig. 5 Numerically predicted and experimentally measured free surface shapes for case E1. (The initial guess is shown for comparison.)
Fig. 6 Effect of preform feed speed on the predicted (solid line) and measured (symbols) free surface shapes
Fig. 8 Effect of the furnace wall temperature on the predicted and measured draw force
Fig. 9 Effect of upstream heating on the predicted free surface shape. A comparison between the results for (solid line) and (dashed line) is shown.
