Jamming modulates coalescence dynamics of shear-thickening colloidal droplets

M. V. R. Sudheer, Sarath Chandra Varma, Aloke Kumar +1

Recent investigations into coalescence dynamics of complex fluid droplets revealed the existence of sub-Newtonian behaviour for polymeric fluids (elastic and shear thinning). We hy…

Sub-Newtonian coalescence in polymeric fluids

Abhineet Singh Rajput, Sarath Chandra Varma, Aloke Kumar

We present a theoretical framework for capturing the coalescence of a pendant drop with a sessile drop in polymeric fluids. The framework is based on the unification of various con…

Elasticity can affect droplet coalescence

Sarath Chandra Varma, Debayan Dasgupta, Aloke Kumar

Recent investigations on the coalescence of polymeric droplets on a solid substrate have reported strong disagreements; the heart of the issue is whether coalescence of polymeric d…

Rheocoalescence: Relaxation time through coalescence of droplets

Sarath Chandra Varma, Abhineet Singh Rajput, Aloke Kumar

Dynamics of the pendant drop coalescing with a sessile drop to form a single daughter droplet is known to form a bridge. The bridge evolution begins with a point contact between th…

Coalescence of polymeric sessile drops on a partially wettable substrate

Sarath Chandra Varma, Aniruddha Saha, Aloke Kumar

Coalescence of sessile polymeric fluid drops on a partially wettable substrate exhibits a transition from inertial to viscoelastic regime at concentration ratio . Our…

Universality in coalescence of polymeric fluid drops

Sarath Chandra Varma, Siddhartha Mukherjee, Aniruddha Saha +3

Coalescence of liquid droplets involves an interplay between capillary forces, viscous forces and inertial forces. Here, we unveil a universal temporal evolution of the neck radius…
