Though the wall shear stress does not undershoot near the die lip, we believe that this upstream undershoot still helps suppress die lip build-up.
Figure 9 compares the computed shear stress undershoot in flared dies with fixed downstream shear rate [[gamma].
1] undershoot (though well before the exit) helps reduce the extrudate swell, thus suppressing die lip build-up.
Hence, if the flared section is too long, the polymer melt will forget its upstream undershoot history and there will be no die drool suppression.

We use the Liu equation to calculate undershoot of the first normal stress difference [N.
