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…

Motion of an air bubble under the action of thermocapillary and buoyancy forces
Manoj Kumar Tripathi, Kirti Chandra Sahu
A novel way to handle surface tension gradient driven flows is developed in the volume-of-fluid (VoF) framework. Using an open source Navier-Stokes solver, {\it Basilisk}, and the…
