The Viscoelastic Swirled Flow in the Confusor [PDF]
Polymers, 2021 A two-dimensional mathematical model for a steady viscoelastic laminar flow in a confusor was developed under the condition of swirled flow imposed at the inlet. Low density polyethylene was considered as a working fluid. Its behavior was described by a two-mode Giesekus model.
