Evaporation of water-in-oil microemulsion droplet
Bal Krishan, Preetika Rastogi, D. Chaitanya Kumar Rao +3
Emulsion fuels have the potential to reduce both particulate matter and NOx emissions and can potentially improve the efficiency of combustion engines. However, their limited stabi…
Elasticity affects the shock-induced aerobreakup of a polymeric droplet
Navin Kumar Chandra, Shubham Sharma, Saptarshi Basu +1
Boger fluids are viscoelastic liquids having constant viscosity for a broad range of shear rates. They are commonly used to separate the effects of liquid elasticity from viscosity…
Evaporation of bacteria-laden surrogate respiratory fluid droplets: On a hydrophilic substrate versus contact-free environment confers differential bacterial infectivity
Amey Nitin Agharkar, Dipasree Hajra, Durbar Roy +4
The transmission of viruses/ bacteria cause infection predominantly via aerosols. The transmission mechanism of respiratory diseases is complex, including direct or indirect contac…
Insights into Spatio-temporal dynamics during shock -- droplet flame interaction
Gautham Vadlamudi, Akhil Aravind, Saini Jatin Rao +1
The study comprehensively investigates the response of a combusting droplet during its interaction with a high-speed transient flow that is imposed by a coaxially propagating blast…
Insights into bubble droplet interactions in evaporating polymeric droplets
Gannena K S Raghuram, Durbar Roy, D Chaitanya Kumar Rao +2
Polymer droplets subjected to a heated environment have significance in several fields ranging from spray drying and powder formation to surface coating. In the present work, we in…
Aerodynamic bag breakup of a polymeric droplet
Navin Kumar Chandra, Shubham Sharma, Saptarshi Basu +1
The aerodynamic breakup of a polymeric droplet in the bag breakup regime is investigated experimentally and compared with the result of the Newtonian droplet. To understand the eff…
