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…
Motion of a sphere in a viscous density stratified fluid
Arun Kumar Varanasi, Ganesh Subramanian
We examine the translation of a sphere in a stably stratified ambient in the limit of small Reynolds () and viscous Richardson numbers (); here, $Re = \frac{ρ…
Linear stability of a rotating liquid column revisited
Pulkit Dubey, Anubhab Roy, Ganesh Subramanian
We revisit the somewhat classical problem of the linear stability of a rigidly rotating liquid column in this communication. Although literature pertaining to this problem dates ba…
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 rotation of a sedimenting anisotropic particle in a linearly stratified ambient
Arun Kumar Varanasi, Navaneeth K. Marath, Ganesh Subramanian
We derive the torque on a spheroid of an arbitrary aspect ratio sedimenting in a linearly stratified ambient. The analysis demarcates regions in parameter space corresponding t…
Inertio-elastic instability of a vortex column
Anubhab Roy, Piyush Garg, Jhumpal Shashikiran Reddy +1
We analyze the instability of a vortex column in a dilute polymer solution at large and with , the elasticity num…
