FIG. 6.

Isothermal planar blowing. (a) Three snapshots of the axis configuration of polymer jet at the dimensionless time , 35, and 50 (the corresponding dimensional times are 0.13 s, 0.3 s, and 0.43 s, respectively). (b) The later snapshot of the polymer jet axis corresponding to the dimensionless time (the corresponding dimensional time is 0.65 s).

(a) Three snapshots of the polymer jet axis in the isothermal planar blowing at the dimensionless time , 35, and 50 (the corresponding dimensional times are 0.13 s, 0.3 s, and 0.43 s, respectively) with the symbols denoting the material elements of the jet. (b) Same in the nonisothermal planar blowing.

Image of FIG. 8.
