Counter-intuitive evaporation in nanofluids droplets due to stick-slip nature
Hari Govindha A., Pallavi Katre, Saravanan Balusamy +2
We experimentally investigate the evaporation characteristics of a sessile ethanol droplet containing AlO and Cu nanoparticles of sizes 25 nm and 75 nm on a heated substrat…
Two-layer channel flow involving a fluid with time-dependent viscosity
Kirti Chandra Sahu
A pressure-driven two-layer channel flow of a Newtonian fluid with constant viscosity (top layer) and a fluid with a time-dependent viscosity (bottom layer) is numerically investig…
Evaporation of sessile ethanol-water droplets on a highly inclined heated surface
Pallavi Katre, Pradeep Gurrala, Saravanan Balusam +2
The evaporation of a binary sessile ethanol-water droplet on an inclined substrate is studied experimentally just below the critical sliding angles for different substrate temperat…
Deformation and breakup of droplets in an oblique continuous air stream
Surendra Kumar Soni, Pavan Kumar Kirar, Pankaj Kolhe +1
We experimentally investigate the deformation and breakup of droplets interacting with an oblique continuous air stream. A high-speed imaging system is employed to record the traje…
Simulations of a weakly conducting droplet under the influence of an alternating electric field
Kirti Chandra Sahu, Manoj Kumar Tripathi, Jay Chaudhari +1
We investigate the electrohydrodynamics of an initially spherical droplet under the influence of an external alternating electric field by conducting axisymmetric numerical simulat…
Shapes and paths of an air bubble rising in quiescent liquids
DM Sharaf, A R Premlata, Manoj Kumar Tripathi +2
Shapes and paths of an air bubble rising inside a liquid are investigated experimentally. About three hundred experiments are conducted in order to generate a phase plot in the Gal…
