On the stick-slip flow from slit and cylindrical dies of a Phan-Thien and Tanner fluid model. II. Linear stability analysis
(2013)During extrusion of viscoelastic fluids various flow instabilities may arise resulting in a distorted free surface. In order to investigate the factors generating these instabilities we performed a linear stability analysis ... -
Some experiences with the slip boundary condition in viscous and viscoelastic flows
(2013)A slip boundary condition (SBC) has been known to occur at solid boundaries in a variety of materials processing including polymer processing. In the present work, implementation of the SBC has been tested for viscous and ...
