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…

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…

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…
