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…
Onset of transient shear banding in viscoelastic shear start-up flows: Implications from linearized dynamics
Shweta Sharma, V. Shankar, Yogesh M. Joshi
We analyze transient dynamics during shear start-up in viscoelastic flows between two parallel plates, with a specific focus on the signatures for the onset of transient shear band…
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…
