A Numerical method for the Viscoelastic Melt Spinning Model with Radial resolutions of Temperature and Stress Fields
(American Chemical Society, 2002-06)
A numerical method to compute the viscoelastic melt-spinning model with radial resolutions of temperature and stress fields is formulated and applied to the low speed range. The starting framework is the reduction of the ...
Modeling Melt Spinning with Stress Induced Crystallization at High Take Up Velocities: Numerical Results for the PET Melt
(Asociación Argentina de Mecánica Computacional, 2002-11)
The purpose of this work is to present a 2-D thermo-rheological model for high take up velocities that can predict numerically in the filament domain, the axial velocity profile together with the radial and axial resolutions ...
Computational Spinning Model to Study Different Expressions Proposed in the Literature for the Elongational Viscosity Evaluation from Spinning Experimental Data
(Asociación Argentina de Mecánica Computacional, 2006-12)
The relation between isothermal elongational flow and other flow kinematics, like shear flow, was of interest since the early stages of rheometry. The main seeking purpose was precisely to achieve the evaluation of the ...
