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…
Liquid Sheet Breakup in Gas-Centered Swirl Coaxial Atomizers
V. Kulkarni, D. Sivakumar, C. Oommen +1
The study deals with the breakup behavior of swirling liquid sheets discharging from gas-centered swirl coaxial atomizers with attention focused toward the understanding of the rol…
An experimental and theoretical investigation of spray characteristics of impinging jets in impact wave regime
Neil S. Rodrigues, Varun Kulkarni, Jian Gao +2
The current study focuses on experimentally and theoretically improving the characterization of the drop size and drop velocity for like-on-like doublet impinging jets. The experim…
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…
An analytical and experimental study of secondary atomization for vibrational and bag breakup modes
Varun Kulkarni
Bag breakup of drops has been a subject of interest for almost over a century. Several issues such as theoretical estimation of the regime boundary marking the onset of such breaku…
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…
Coalescence and spreading of drops on liquid pools
Varun Kulkarni, Venkata Yashasvi Lolla, Suhas Rao Tamvada +2
Oil spills have posed a serious threat to our marine and ecological environment in recent times. Containment of spills proliferating via small drops merging with oceans/seas is esp…
Boiling transitions during droplet contact on superheated nano/micro-structured surfaces
Navid Saneie, Varun Kulkarni, Kamel Fezzaa +2
Manipulating surface topography is one of the most promising strategies for increasing the efficiency of numerous industrial processes involving droplet contact with superheated su…
