Maximal spreading of impacting viscoelastic droplets
Orr Avni, Dongyue Wang, Mithun Ravisankar +1
Droplet impact and spreading on solid substrates are well understood for Newtonian fluids, yet how viscoelasticity alone modifies the maximal spreading remains unclear. To identify…

Low Reynolds number pumping near an elastic half space
Avery Trevino, Thomas R. Powers, Roberto Zenit +1
Previous studies on peristalsis, the pumping of fluid along a channel by wave-like displacements of the channel walls, have shown that the elastic properties of the channel and the…

Velocity fluctuations for bubbly flows at small Re
Mithun Ravisankar, Roberto Zenit
We experimentally investigate the effect of Reynolds number (Re) on the turbulence induced by the motion of bubbles in a quiescent Newtonian fluid at small Re. The energy spectra,…
