Shear localization in large amplitude oscillatory shear (LAOS) flows of particulate suspensions
نویسندگان
چکیده
Significant shear localization, observed as substantial concentration gradients, is discovered in large amplitude oscillatory (LAOS) simulations of a complex fluid planar Couette setup. The localization demonstrated to occur due the inertial effects imposed by LAOS, which serve perturbations nonlinear equations describing structural response shear. Additionally, criterion for onset this presented.

Probing shear-banding transitions of the VCM model for entangled wormlike micellar solutions using large amplitude oscillatory shear (LAOS) deformations
We explore the use of Large Amplitude Oscillatory Shear (LAOS) deformation to probe the dynamics of shear-banding in soft entangled materials, primarily wormlike micellar solutions which are prone to breakage and disentanglement under strong deformations. The state of stress in these complex fluids is described by a class of viscoelastic constitutive models which capture the key linear and nonl...
متن کاملDynamic Shear Rheology of Thixotropic Suspensions: Comparison of Structure-Based Models with Large Amplitude Oscillatory Shear Experiments
Rheological measurements on a model thixotropic suspension developed by Dullaert and Mewis are performed, including large amplitude oscillatory shear (LAOS) flow, shear flow reversal, and a novel unidirectional LAOS flow, to provide an extended rheological data set for testing constitutive models. A new structure-based model is developed by improving the elastic stress component in the Delaware...
متن کاملNumerical simulation of a drop undergoing large amplitude oscillatory shear
The study of drop deformation in a time-dependent flow has received less attention compared to elongational and shear flows (Rallison 1984; Stone 1994; Li et al. 2000). One class of time-dependent flow, which can be achieved experimentally and analyzed numerically is that of an initially spherical drop, which deforms in response to an applied oscillatory shear. Figure 1 shows a schematic of the...
متن کاملStrain-rate frequency superposition in large-amplitude oscillatory shear.
In a recent work, Wyss [Phys. Rev. Lett. 98, 238303 (2007)] have noted a property of "soft solids" under oscillatory shear, the so-called strain-rate frequency superposition. We extend this study to the case of soft solids under large-amplitude oscillatory shear (LAOS). We show results from LAOS studies in a monodisperse hydrogel suspension, an aqueous gel, and a biopolymer suspension and show ...
متن کاملLarge amplitude oscillatory shear properties of human skin.
Skin is a complex multi-layered tissue, with highly non-linear viscoelastic and anisotropic properties. Thus far, a few studies have been performed to directly measure the mechanical properties of three distinguished individual skin layers; epidermis, dermis and hypodermis. These studies however, suffer from several disadvantages such as skin damage due to separation, and disruption of the comp...
