Competing thermal and solutal advection decelerates droplet evaporation on heated surfaces

Kaushal, A.; Jaiswal, V.; Mehandia, V.; Dhar, P. (2022-06-26)

We report the complex evaporation kinetics of saline sessile droplets on surfaces with elevated temperatures. Our previous studies show that on non-heated substrates, saline sessile droplets evaporate faster compared to ...
Competitive electrohydrodynamic and electrosolutal advection arrests evaporation kinetics of droplets

Jaiswal, V.; Singh, S.; Harikrishnan, A. R.; Dhar, P. (2021-06-12)

: This article reports the hitherto unreported phenomenon of arrested evaporation dynamics in pendant droplets because of electric field stimulus. The evaporation kinetics of pendant droplets of electrically conducting ...
Electromagnetic field orientation and characteristics governed hydrodynamics within pendent droplets

Dhar, P.; Jaiswal, V.; Harikrishnan, A.R. (2022-09-24)

This article reports the dominant governing role played by the direction of electric and magnetic fields on the internal advection pattern and strength within salt solution pendent droplets. The literature shows that solutal ...
Electromagnetic field orientation and dynamics governs advection characteristics within pendent droplets

Dhar, P.; Jaiswal, V.; Harikrishnan, A.R. (2018-12-27)

The article reports the domineering governing role played by the direction of electric and magnetic fields on the internal advection pattern and strength within salt solution pendant droplets. Literature shows that solutal ...
Influence of competitive electro- and ferro-hydrodynamics on droplet vaporization phenomenology

Dhar, P.; Jaiswal, V.; Chate, H.; Maganti, L.S. (2022-11-21)

Modification and control of the vaporization kinetics of microfluidic droplets can find utilitarian implications in several scientific and technological applications. The article reports the control over the vaporization ...
Interplay of electro-thermo-solutal advection and internal electrohydrodynamics governed enhanced evaporation of droplets

Jaiswal, V.; Dhar, P. (2019-08-24)

The article experimentally examines and theoretically establishes the influence of electric field on the evaporation kinetics of pendant droplets. It is observed that the evaporation of saline-pendant droplets can be ...
Ionic solubility and solutal advection governed augmented evaporation kinetics of salt solution pendant droplets

Jaiswal, V.; Harikrishnan, A.R.; Khurana, G.; Dhar, P. (2018-12-21)

The presence of dispersed inclusions is known to modify the interfacial characteristics in liquids by adsorption–desorption of the ions at interfaces. The present article reports the influencing role of dissolved ions ...
Magnetohydrodynamics- and magnetosolutal-transport-mediated evaporation dynamics in paramagnetic pendant droplets under ﬁeld stimulus

Jaiswal, V.; Dwivedi, R.K.; Harikrishnan, A.R.; Dhar, P. (2018-08-31)

Evaporation kinetics of pendant droplets is an area of immense importance in several applications, in addition to possessing rich ﬂuid dynamics and thermal transport physics. This article experimentally and analytically ...
Soluto-thermo-hydrodynamics influenced evaporation kinetics of saline sessile droplets

Kaushal, A.; Jaiswal, V.; Mehandia, V.; Dhar, P. (2021-06-12)

The present article experimentally and theoretically probes the evaporation kinetics of sessile saline droplets. Observations reveal that presence of solvated ions leads to modulated evaporation kinetics, which is further ...
Superhydrophobic surface curvature dependence of internal advection dynamics within sessile droplets

Dhar, P.; Khurana, G.; Raman, H. A.; Jaiswal, V. (2021-08-26)

Sessile droplets seated on superhydrophobic surfaces are known to exhibit internal circulation patterns. The present article experimentally demonstrates and theoretically confirms, for the very first time, that the nature ...
