The stability of viscoelastic fluids in complex flows : the role of shear and extensional rheology

Rothstein, Jonathan P. (Jonathan Philip), 1974-Massachusetts Institute of Technology2001

Understanding the flow of polymeric fluids is important for optimizing commercial processes such as injection molding and fiber spinning. The combination of streamwise curvature and elastic normal stresses can lead to the onset of elastic flow instabilities, severely rate-limiting such processes. …
