Asymmetric freezing of a sliding droplet on an inclined surface
Sivanandan Kavuri, George Karapetsas, Chander Shekhar Sharma +1
We investigate the asymmetric freezing of a liquid droplet sliding on an inclined cold surface using numerical simulations based on the lubrication approximation. The combined effe…
Evaporation of a freely floating droplet in an airstream: effects of temperature, humidity, and shape oscillations
Shubham Chakraborty, Someshwar Sanjay Ade, Aman John Tudu +2
We present a comprehensive experimental and theoretical investigation of the evaporation dynamics of freely levitated water droplets in an upward airstream under varying temperatur…
Effect of velocity, fluid properties and drop shape on coalescence and neck oscillation
Manas Ranjan Behera, Hiranya Deka, Kirti Chandra Sahu +1
We perform axisymmetric numerical simulations to investigate the coalescence dynamics of a liquid drop in a deep liquid pool. This study aims to generalize the mechanisms of partia…
Unveiling crown-finger instability of a non-spherical drop impacting a liquid surface
Nagula Venkata Anirudh, Sachidananda Behera, Kirti Chandra Sahu
We present a three-dimensional numerical study of the splashing dynamics of non-spherical droplets impacting a quiescent liquid film, covering a wide range of aspect ratios (Ar) an…
A new instability driven by the combined effect of wind stress and rotation in a sheared liquid layer
S. Preethi, Ankush Kamboj, Ramkarn Patne +2
We examine the linear stability of a shear flow driven by wind stress at the free surface and rotation at the lower boundary, mimicking oceanic flows influenced by surface winds an…
Evaporation Dynamics of Completely Pinned and Partially Pinned Sessile Droplets in Multi-Droplet Configurations
A. Hari Govindha, Sayak Banerjee, Saravanan Balusamy +1
The evaporation of sessile droplets placed in close proximity is influenced by complex vapor-vapor interactions, producing a shielding effect that can significantly extend droplet…
