Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
Distinguishing thixotropy from viscoelasticity
Mayank Agarwal, Shweta Sharma, V. Shankar +1
Owing to nonlinear viscoelasticity, materials often show characteristic features that resemble those of thixotropy. This issue has been debated in the literature over the past seve…
A continuous pathway between the elasto-inertial and elastic turbulent states in viscoelastic channel flow
Mohammad Khalid, V. Shankar, Ganesh Subramanian
We show that viscoelastic plane Poiseuille flow becomes linearly unstable in the absence of inertia, in the limit of high elasticities, for ultra-dilute polymer solutions. While in…
The center-mode instability of viscoelastic plane Poiseuille flow
Mohammad Khalid, Indresh Chaudhary, Piyush Garg +2
A modal stability analysis shows that plane Poiseuille flow of an Oldroyd-B fluid becomes unstable to a `center mode' with phase speed close to the maximum base-flow velocity, $U_{…
Transient start-up dynamics and shear banding in aging soft glassy materials: Rate-controlled flow field
Anika Jain, Ramanish Singh, Lakshmi Kushwaha +2
We study the transient start-up dynamics of a fluidity model which captures the rheological behavior of aging soft glassy materials, in a rectilinear shear flow upon application of…
