Past and New Developments in the Numerical Simulation of Polymer Flows with the K-BKZ Model

摘要

In recent years good progress has been achieved in the viscoelastic simulation of polymeric liquids by using integral constitutive equations of the K-BKZ type. This is particularly true for the modeling of polymer solutions and melts with a spectrum of relaxation times. Considerable success has been achieved with a particular type of the K-BKZ integral equation, the PSM model. This equation has been used to predict several well-known viscoelastic phenomena for polymer melts. The present work will review past and up-to-date achievements and will discuss future developments and challenges in the field of computational non-Newtonian fluid dynamics.
