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…
