Shock induced atomisation of a liquid metal droplet
Shubham Sharma, Navin Kumar Chandra, Aloke Kumar +1
The present study uses Galinstan as a test fluid to investigate the shock-induced aerobreakup of a liquid metal droplet in a high Weber number regime (We ~ 400 - 8000). Atomization…
Depth from Defocus Technique Applied to Unsteady Shock-Drop Secondary atomization
Shubham Sharma, Saini Jatin Rao, Navin Kumar Chandra +3
The two-sensor depth from defocus (DFD) technique for the measurement of drop sizes in a spray is further developed to achieve higher spatial and temporal resolution, to improve es…
Newtonian coalescence in colloidal and non-colloidal suspensions
Abhineet Singh Rajput, Sarath Chandra Varma, Aloke Kumar
Coalescence event in pendant and sessile drop is distinguished by the formation and evolution of the liquid bridge created upon singular contact. The bridge radius, , is known t…
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…
Contact angle hysteresis can modulate the Newtonian rod climbing effect
Navin Kumar Chandra, Kaustuv Lahiri, Aloke Kumar
The present work investigates the role of contact angle hysteresis at the liquid-liquid-solid interface (LLS) on the rod climbing effect of two immiscible Newtonian liquids using e…
Shock induced aerobreakup of a polymeric droplet
Navin Kumar Chandra, Shubham Sharma, Saptarshi Basu +1
Droplet atomization through aerobreakup is omnipresent in various natural and industrial processes. Atomization of Newtonian droplets is a well-studied area; however, non-Newtonian…
