Collisional ferrohydrodynamics of magnetic fluid droplets on superhydrophobic surfaces

Sahoo, N.; Khurana, G.; Samanta, D.; Dhar, P. (2021-08-01)

The study reports the aspects of post-impact hydrodynamics of ferrofluid droplets on superhydrophobic (SH) surfaces in the presence of a horizontal magnetic field. A wide gamut of dynamics was observed by varying the ...
Electrohydrodynamics of dielectric droplet collision on different wettability surfaces

Sahoo, N.; Samanta, D.; Dhar, P. (2022-08-18)

In this article, we report the experimental and semi-analytical findings to elucidate the electrohydrodynamics (EHD) of a dielectric liquid droplet impact on superhydrophobic (SH) and hydrophilic surfaces. A wide range of ...
Ferro and electrohydrodynamics of impacting droplets

Sahoo, N. (2022-11-24)

The aim of this thesis is to understand the external field induced (gravitational, electric and magnetic fields) spreading dynamics of drops on surfaces of varying degrees of wettability. In pursuit of this, the present ...
Non–fourier thermal transport induced structural hierarchy and damage to collagen ultrastructure subjected to laser irradiation

Sahoo, N.; Narasimhan, A.; Dhar, P.; Das, S.K. (2018-12-31)

Comprehending the mechanism of thermal transport through biological tissues is an important factor for optimal ablation of cancerous tissues and minimising collateral tissue damage. The present study reports detailed mapping ...
Phenomenology of droplet collision hydrodynamics on wetting and nonwetting spheres

Khurana, G.; Sahoo, N.; Dhar, P. (2019-08-23)

In this study, the spreading characteristics of water droplets impacted on a solid spherical target have been investigated experimentally and theoretically. Droplet impact and postimpact feature studies have been conducted ...
Post impact droplet hydrodynamics on inclined planes of variant wettabilities

Sahoo, N.; Khurana, G.; Harikrishnan, A.R.; Samanta, D.; Dhar, P. (2020-03-13)

Experimental investigations were carried out to elucidate the roles of surface wettability and inclination on the post-impact dynamics of droplets. The maximum spreading diameter and spreading time were found to decrease ...
Post-collision hydrodynamics of droplets on cylindrical bodies of variant convexity and wettability

Khurana, G.; Sahoo, N.; Dhar, P. (2021-08-26)

Droplet impact, dynamics, wetting, and spreading behavior on surfaces impose rich and interesting physics, in addition to extensive understanding of processed employing droplets and sprays. The physics and mechanisms ...
Vertical magnetic field aided droplet-impact- magnetohydrodynamics of ferrofluids

Sahoo, N.; Dhar, P.; Samanta, D. (2021-12-19)

In this present article, we have investigated the magnetohydrodynamics of ferrofluid droplets impacting on different wettability surfaces, in the presence of a vertical magnetic field. The spreading dynamics was studied for ...
