When considering highly viscous materials, this geometric constraint is likely to cause not only equipment (extruder, gear pump, and/or multiplier) failure due to increased pressure drops originating in the compressive section, but is also likely to induce the previously described flow instabilities due to the nonuniform flow paths and residence times inside the multiplier die.

To deal with the nonuniform flow resistance effect, the porous media zone with half real tubes on both sides of the porous media zone is applied (see Figure 2).
The analysis identified nonuniform flow through the hoppers as well as temperature gradients of up to 80[degrees] C/144 [degrees] F from the center to the outside.

Nonuniform flow around the core pin causes the pin to shift during the injection and pack phases of the cycle, and this shifting causes wall-thickness variation, resulting in both structural and cosmetic defects.
The axial pressure drop along the inner cavity causes a nonuniform flow distribution.
As discussed, the fans tested in the present study generated a nonuniform flow.
The increased sound level is likely due to the nonuniform flow in the diffuser, air striking the diffuser louvers at unexpected angles, and increased airflow velocity on three sides of the diffuser.

BEM applications range from the classical study of a rising drop in an otherwise quiescent fluid, to drop breakup and coalescence (15, 16), the influence of nonuniform flow on drop deformation in shear (17, 18) or extensional flow (19-21).
Nonuniform flow in the primary slot is subsequently considered as a perturbation.
