Splashing velocity of a viscous liquid squeezed between two parallel disks
Navin Kumar Chandra, Pierre Perrier, David Brutin
Squeezing of a liquid film between two approaching solid surfaces can generate a high-speed peripheral splash. Despite extensive studies on squeeze-film hydrodynamics, quantitative…

Elasto-viscous regime in coalescence of viscoelastic droplets
Pallavi Katre, Bimalendu Mahapatra, Manaswita Karmakar +3
We report a regime transition in the coalescence of concentrated polymeric droplets in a pendant-pendant configuration. While Newtonian droplet coalescence has been extensively stu…

Elasticity affects the shock-induced aerobreakup of a polymeric droplet
Navin Kumar Chandra, Shubham Sharma, Saptarshi Basu +1
Boger fluids are viscoelastic liquids having constant viscosity for a broad range of shear rates. They are commonly used to separate the effects of liquid elasticity from viscosity…
