Waves dictate the yo-yoing decay of a viscoelastic mixing layer
Giulio Foggi Rota, Piyush Garg, Jason Tang +1
We find that waves develop in a time-decaying mixing layer of viscoelastic fluid, leading the mean-flow to yo-yo. This is in sharp contrast with Newtonian fluids, where laminar mix…

Orientation dynamics of a spheroid in the simple shear flow of a weakly elastic fluid
Pavan Kumar Singeetham, Deepak Madival, Piyush Garg +1
We investigate the orientation dynamics of a neutrally buoyant spheroid, of an arbitrary aspect ratio (), freely rotating in a weakly viscoelastic fluid undergoing simple shear…
