Issues In Viscoelastic Fluid Mechanics

Annual Review of Fluid Mechanics, 1990
nt transient that may be many orders of magnitude longer than time scales associated with instrument inertia. Intrinsic material time scales can be identified with the dynamics of the macro­ molecular chains. Shaping processes for polymeric materials are usually carried out in the liquid state, often over times that are rapid relative to those ...

Viscoelastic Conjugated Polymer Fluids

Angewandte Chemie International Edition, 2019
AbstractThe introduction of optoelectronic functions into viscoelastic polymers can yield highly sophisticated soft materials for biomedical devices and autonomous robotics. However, viscoelasticity and excellent optoelectronic properties are difficult to achieve because the presence of a large number of π‐conjugated moieties drastically stiffens a ...

Sink Flows of Viscoelastic Fluids

Journal of Rheology, 1986
Both two-constant and three-parameter upper convected Maxwell-Oldroyd models of viscoelastic fluids are used in this analysis of spherical and cylindrical sink flows. For spherical sink flows the stresses rise rapidly initially and the stress levels attained are large but bounded, while for cylindrical sink flows the viscoelastic stresses are modest ...

Controlled Viscoelastic Carbon Nanotube Fluids

Journal of the American Chemical Society, 2008
It is generally assumed that some qualitative factors, including high organic fraction, size, density, and surface chemistry of the core etc., will dominate the liquid-like behavior of the hybrid nanofluids. For quasi one-dimensional PEG-functionalized carbon nanotubes (PEG-CNTs), this paradigm may be quite different.

Incompressible Viscoelastic Fluids

1994
In Part I, we discussed in detail the foundations of the bracket description of dynamical behavior, demonstrating how the generalized bracket is linked to the theories of both Hamiltonian mechanics and irreversible thermodynamics. Now it is time to discuss the various applications towards seemingly complex systems which are the main focus of this book.
