Modeling the Melt Spinning of Polyethylene Terephthalate
(Sage Publications Ltd, 2000-04)
A model is formulated to describe quantitatively the melt spinning of a polyethylene terephthalate (PET) within the low range of take up velocities. The rheology of the polymer melt is described with the Phan-Thien and ...
Aging, rejuvenation and thixotropy in yielding magnetorheological fluids
(Springer, 2013-05)
The yielding behavior of dilute magnetorheological (MR) fluids has been investigated using creep–recovery tests. At very low stress levels, MR fluids behave in the linear viscoelastic regime as demonstrated by the fact ...
Effect of pH on the rheological response of reconstituted gastric mucin
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-05-01)
The rheological response of reconstituted gastric mucin was studied by time dependent rheological experiments as function of pH. Mucin concentrations of 5% and 10% were prepared in buffer dispersions at pH of 1.15, 2.00, ...
The avalanche effect of an elasto-viscoplastic thixotropic material on an inclined plane
(Elsevier B.V., 2017-09-01)
The so-called avalanche effect is one of the fingerprints of thixotropic materials. This self-reinforcing process where the decrease in viscosity, due to a rejuvenation process triggered by a stress field, induces a motion ...
Relationships between rheological properties, texture and structure of apple (Granny Smith var.) affected by blanching and/or osmotic dehydration
(Springer, 2013-03)
The objective of this work was to evaluate and correlate rheological properties (small-scale dynamic oscil- latory and creep/recovery measurements and large-scale compression force-deformation testing), texture (sensory ...
Impact of combined ascorbic acid/CaCl2, hydrogen peroxide and ultraviolet light treatments on structure, rheological properties and texture of fresh-cut pear (William var.)
(Elsevier, 2013-01)
This work aimed to evaluate and correlate rheological properties (dynamic oscillatory, creep/recovery and double compression tests), texture (sensory evaluation) and structure (optical and transmission electron microscopy ...
Relationships Between Texture and Rheological Properties in Blanched Apple Slices (var. Granny Smith) Studied by Partial Least Squares Regression
(Springer, 2014-01)
The effect of steam blanching (90 or 150 s) on linear viscoelastic and compression properties, sensory texture, and micro- and ultrastructure of cut apple was analyzed. All apple samples showed a solid behavior (storage ...
