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…
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_{…
An anisotropic particle in a simple shear flow: an instance of chaotic scattering
Mahan Raj Banerjee, Ganesh Subramanian
In the Stokesian limit, the streamline topology around a single neutrally buoyant sphere is identical to the topology of pair-sphere pathlines, both in an ambient simple shear flow…
Linear instability of viscoelastic pipe flow
Indresh Chaudhary, Piyush Garg, Ganesh Subramanian +1
A modal stability analysis shows that pressure-driven pipe flow of an Oldroyd-B fluid is linearly unstable to axisymmetric perturbations, in stark contrast to its Newtonian counter…
Orientation Dynamics of Sedimenting Anisotropic Particles in Turbulence
Prateek Anand, Samriddhi Sankar Ray, Ganesh Subramanian
We examine the dynamics of small anisotropic particles (spheroids) sedimenting through homogeneous isotropic turbulence using direct numerical simulations and theory. The gravity-i…
