F. Rodríguez-González, J. Pérez-González and B.M. Marín-Santibáñez
The knowledge of the flow kinematics of polymer melts is relevant for their processing.
In this work, a description is performed of the flow kinematics of a low-density polyethylene under extrusion in a capillary die.
This work shows the reliability of the PIV technique to describe the flow behavior of polymer melts.
In this work, a procedure is described to obtain the flow and viscosity curve for a polymer from its velocity profiles.
