Elasto-hydrodynamics of droplet-pool-interactions
Md Sultan, Purbarun Dhar
In Newtonian fluids, impact of a droplet on a liquid pool births a cavity, crown, capillary waves, and Worthington jet. The corresponding hydrodynamic events for elastic or Boger f…
Interfacial-Thermo-Fluid-Adhesion Dynamics of Evaporating Capillary Bridges between Curved Surfaces
Arnov Paul, Subhadeep Mondal, Purbarun Dhar
We probe the evaporation mechanism, and the associated adhesion dynamics of liquid capillary bridges connecting two curved, solid substrates. The coupled thermo fluid species trans…
The magneto-Leidenfrost effect in ferrofluid droplets
Abhishek Kumar Jaiswal, Neeladri Sekhar Bera, Purbarun Dhar
The dynamic Leidenfrost effect LFE and behaviour of impinging colloidal droplets is strongly influenced by the impact and spreading paradigms. LFE actuated rebound and levitation o…
Evaporative thermo-fluidics and deposition patterns in surface-active droplets
Randeep Ravesh, A R Harikrishnan, Purbarun Dhar
We investigate the thermo solutal transport phenomena and deposition patterns during the evaporation of surfactant laden droplets experimentally and through theoretical scaling bas…
Ferro-hydrodynamics of droplet necking filaments
Neeladri Sekhar Bera, Apurba Roy, Purbarun Dhar
We explore the necking, filament thinning, and pinchoff dynamics of ferrofluid droplets within a magnetic field, via a simple and low-cost experimental method. In our studies, both…
The fluid dynamics of liquid mushrooms
Akshay Manoj Bhaskaran, Arnov Paul, Apurba Roy +2
Droplets that impact the surface of a deep liquid pool may form a vertical jet after the cavity formation event, provided they have sufficient impact energy. Depending on the assoc…
