Modeling of Nonisothermal Viscoelastic Slender Jet and Thin Sheet Flows.
Abstract
The central theme in the study for viscoelastic flows is the modeling of thin filament flows. In particular, we want to address the issues that industries are interested in such as derivation and evaluation of reliable low-dimensional models, temperature distribution along the spinline and radial variation in fiber spinning processes and modeling of crystallization in fiber spinning processes. Our platform in addressing these issues is based on the Maxwell, Johnson-Segalman constitutive equations for the extra stress and their modifications for nonisothermal flows. Specifically, we developed a systematic way to derive and evaluate 1-D models of Maxwell and Johnson-Segalman flows, derived hybrid 2-D nonisothermal models for temperature dependent spinning processes, and studied linear and nonlinear stabilities of the flows in different geometries.
