Magneto-coalescence phenomena in colliding ferrofluid droplets
Neeladri Sekhar Bera, Abhishek Kumar Jaiswal, Devranjan Samanta +1
We explore the collision hydrodynamics of a ferrofluid droplet falling freely onto a sessile droplet of the same liquid, in the presence of a horizontal magnetic field; a configura…
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…
