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…
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,…
The Fluid Mechanics of Splatter Painting
Diego Ávila-García, Carlos Salazar-Martín, Javier Rodríguez-Rodríguez +3
In splatter painting, a collection of liquid droplets is projected onto the substrate by imposing a controlled acceleration to a paint-loaded brush. This work aims at unraveling th…
The presence of surfactants controls the stability of bubble chains in carbonated drinks
Omer Atasi, Mithun Ravisankar, Dominique Legendre +1
Bubbles appear when a carbonated drink is poured in a glass. Very stable bubble chains are clearly observed in champagne, showing an almost straight line from microscopic nucleatio…
Hydrodynamic interaction of a bubble pair in viscoelastic shear-thinning fluids
Mithun Ravisankar, Alam Garciduenas Correa, Yunxing Su +1
We experimentally investigate the interaction between a pair of bubbles ascending in a stagnant viscoelastic shear-thinning fluid. In particular, we focus on the effect of bubble s…
