Collision of two drops moving in the same direction
Ashwani Kumar Pal, Kirti Chandra Sahu, Santanu De +1
The collision dynamics of two drops of the same liquid moving in the same direction has been studied numerically. A wide range of radius ratios of trailing drop and leading drop ($…
Modeling binary collision of evaporating drops
Ashwani Kumar Pal, Kirti Chandra Sahu, Gautam Biswas
We investigate the interactions between two drops in a heated environment and analyze the effect of evaporation on bouncing, coalescence and reflexive separation phenomena. A relia…
Freezing of sessile droplet and frost halo formation
Sivanandan Kavuri, George Karapetsas, Chander Shekhar Sharma +1
The freezing of a sessile droplet unveils fascinating physics, characterised by the emergence of a frost halo on the underlying substrate, the progression of the liquid-ice interfa…
Universal scaling law for electrified sessile droplets on a lyophilic surface
Dipin S. Pillai, Kirti Chandra Sahu
Electrified sessile droplets on solid surfaces are ubiquitous in nature as well as several practical applications. Although the influence of electric field on pinned sessile drople…
An investigation on the impact of two vertically aligned drops on a liquid surface
Akash Paul, Bahni Ray, Kirti Chandra Sahu +1
The dynamics of two vertically coalescing drops and a pool of the same liquid have been investigated using a Coupled Level Set and Volume of Fluid (CLSVOF) method. Such a configura…
Dynamics of an evaporating drop migrating in a Poiseuille flow
Anubhav Dubey, Kirti Chandra Sahu, Gautam Biswas
The evaporation of a liquid drop of initial diameter (Ddrop) migrating in a tube of diameter (D0) is investigated using the coupled level set and volume of fluid (CLSVOF) method fo…
Effect of viscosity on the dynamics of a non-equilibrium bubble in free-field and near a free-surface
Y. S. Kannan, Saravanan Balusamy, Badarinath Karri +1
The effect of viscosity on the behaviour of a non-equilibrium bubble is investigated experimentally, in two scenarios; firstly, when the bubble is generated in the bulk of the flui…
An experimental investigation of droplet morphology in swirl flow
Pavan Kumar Kirar, Surendra Kumar Soni, Pankaj S. Kolhe +1
The interaction of a droplet with a swirling airstream is investigated experimentally by shadowgraphy and particle image velocimetry techniques. In swirl flow, the droplet experien…
Mixed convection instability in a viscosity stratified flow in a vertical channel
Ankush, P. A. L. Narayana, K. C. Sahu
The present study examines the linear instability characteristics of double-diffusive mixed convective flow in a vertical channel with viscosity stratification. The viscosity of th…
Physics of drying complex fluid drop: flow field, pattern formation, and desiccation cracks
Ranajit Mondal, Hisay Lama, Kirti Chandra Sahu
Drying complex fluids is a common phenomenon where a liquid phase transforms into a dense or porous solid. This transformation involves several physical processes, such as the diff…
Size distribution of a drop undergoing breakup at moderate Weber numbers
Someshwar Sanjay Ade, Lakshmana Dora Chandrala, Kirti Chandra Sahu
The size distribution of child droplets resulting from a dual-bag fragmentation of a water drop is investigated using shadowgraphy and digital in-line holography techniques. It is…
Stability and retention force factor for binary-nanofluid sessile droplets on a inclined substrate
Pallavi Katre, Sayak Banerjee, Saravanan Balusamy +1
We investigate the retention force factor of sessile droplets of pure (ethanol) and binary (water-ethanol) fluids laden with alumina nanoparticles placed on a critically inclined s…
