Abstract

fetched live from OpenAlex

Abstract It is argued that the assumption of negligible temperature gradients across the thickness in blown film extrusion is not valid in the vicinity of the die exit. Numerical simulation of heat transfer involving convection and radiation shows significant temperature differences between the inside and outside film surfaces, which gradually decrease and eventually become negligible near the frost line. The differences are influenced by the magnitude of local heat transfer coefficients. In blown film lines having internal bubble cooling (IBC), temperature gradients in the thickness direction may be reduced, but still they cannot be considered negligible for typical production rates. © 2005 Wiley Periodicals, Inc.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
