On interdependence of instabilities and average drop sizes in bag breakup
Varun Kulkarni, Nikhil Shirdade, Neil Rodrigues +2
A drop exposed to cross flow of air experiences sudden accelerations which deform it rapidly ultimately proceeding to disintegrate it into smaller fragments. In this work, we exami…
Increased solidification delays fragmentation and suppresses rebound of impacting drops
Varun Kulkarni, Suhas Tamvada, Nikhil Shirdade +4
The splat formed after drop impact on supercooled solid surfaces sticks to it. On the contrary, a sublimating supercooled surface such as dry ice inhibits pinning and therefore eff…
Bag breakup of low viscosity drops in the presence of a continuous air jet
Varun Kulkarni, Paul E. Sojka
This work examines the breakup of a single drop of various low viscosity fluids as it deforms in the presence of continuous horizontal air jet. Such a fragmentation typically occur…
Bursting Drops
Varun Kulkarni, Venkata Yashasvi Lolla, Suhas Tamvada +1
For decades, researchers worldwide have investigated phenomena related to natural, artificial oil leakages such as oil drop formation within water bodies, their rise, and oil slick…
Modulating outcomes of oil drops bursting at a water-air interface
Varun Kulkarni, Suhas Tamvada, Yashasvi Venkata Lolla +1
Recent studies have shown that capillary waves generated by bursting of an oil drop at the water-air interface produces a daughter droplet inside the bath while part of it floats a…
