Magnetoelastic effect in impact dynamics of nonNewtonian ferrofluid droplets
Gudlavalleti V V S Vara Prasad, Purbarun Dhar, Devranjan Samanta
In this article, we propose, with the aid of detailed experiments and scaling analysis, the existence of magneto-elastic effects in the impact hydrodynamics of non-Newtonian ferrof…
Suppressed Leidenfrost phenomenon during impact of elastic fluid droplets
Purbarun Dhar, Soumya Ranjan Mishra, Ajay Gairola +1
The present article highlights the role of non-Newtonian (elastic) effects on the droplet impact phenomenology at temperatures considerably higher than the boiling point, especiall…
Hydrodynamics of magnetic fluid droplets on superhydrophobic surfaces
Nilamani Sahoo, Gargi Khurana, Devranjan Samanta +1
The study reports the aspects of postimpact hydrodynamics of ferrofluid droplets on superhydrophobic SH surfaces in the presence of a horizontal magnetic field. A wide gamut of dyn…
Onset of rebound suppression in non Newtonian droplets post impact on superhydrophobic surfaces
Purbarun Dhar, Soumya Ranjan Mishra, Devranjan Samanta
Droplet deposition after impact on superhydrophobic surfaces has been an important area of study in recent years due to its potential application in reduction of pesticides usage.…
Interplay of substrate inclination and wettability on droplet impact dynamics
Nilamani Sahoo, Gargi Khurana, A R Harikrishnan +2
Experimental investigations were carried out to elucidate the role of surface wettability and inclination on the post impact dynamics of droplets. Maximum spreading diameter and sp…
Symmetric shear banding and swarming vortices in bacterial "superfluids"
Shuo Guo, Devranjan Samanta, Yi Peng +2
Bacterial suspensions--a premier example of active fluids--show an unusual response to shear stresses. Instead of increasing the viscosity of the suspending fluid, the emergent col…
