Shapes of a filament on the surface of a bubble
S Ganga Prasath, Joel Marthelot, Rama Govindarajan +1
The shape assumed by a slender elastic structure is a function both of the geometry of the space in which it exists and the forces it experiences. We explore by experiments and the…
Wetting and wrapping of a floating droplet by a thin elastic filament
S Ganga Prasath, Joel Marthelot, Narayanan Menon +1
We study the wetting of a thin elastic filament floating on a fluid surface by a droplet of another, immiscible fluid. This quasi-2D experimental system is the lower-dimensional co…
Waves, Algebraic Growth and Clumping in Sedimenting Disk Arrays
Rahul Chajwa, Narayanan Menon, Sriram Ramaswamy +1
An array of spheres descending slowly through a viscous fluid always clumps [J.M. Crowley, J. Fluid Mech. {\bf 45}, 151 (1971)]. We show that anisotropic particle shape qualitative…
Attraction-induced jamming in the flow of foam through a channel
Karthik Menon, Rama Govindarajan, Shubha Tewari
We study the flow of a pressure-driven foam through a straight channel using numerical simulations, and examine the effects of a tuneable attractive potential between bubbles. This…
Oscillatory settling in wormlike-micelle solutions: bursts and a long time scale
Nitin Kumar, Sayantan Majumdar, Aditya Sood +3
We study the dynamics of a spherical steel ball falling freely through a solution of entangled wormlike-micelles. If the sphere diameter is larger than a threshold value, the settl…
Do liquid drops roll or slide on inclined surfaces?
Sumesh P. Thampi, Ronojoy Adhikari, Rama Govindarajan
We study the motion of a two-dimensional droplet on an inclined surface, under the action of gravity, using a diffuse interface model which allows for arbitrary equilibrium contact…
