Dynamics of liquid jet breakup and droplet size distribution in a crossflow airstream
Gowri Padmaja Majji, Aman John Tudu, Lakshmana Dora Chandrala +1
The fragmentation of a liquid jet in a crossflowing airstream arises from a complex interplay between aerodynamic forcing and interfacial instabilities acting across a wide range o…
Vortex ring formation from the interaction of a cavitation bubble with a confined air bubble: experiments and a timing criterion
Charul Gupta, Yashwant Singh, Lakshmana D Chandrala +2
We study vortex ring formation arising from the interaction between a cavitation bubble and a confined air bubble in a cylindrical blind hole, using high-speed shadowgraphy imaging…
Inertial effects on flow dynamics near a moving contact line
Charul Gupta, Rishabh Sharma, Tejasvi Hegde +3
This study investigates the role of inertia in moving contact lines using experiments, theoretical analysis, and numerical simulations. Experiments are conducted using a plate imme…
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…
Jet breakup dynamics of viscoelastic carboxymethyl cellulose solutions
Ketan Vinayak Warghat, Yogesh Biswal, Sukesh Sharma +3
We experimentally investigate the breakup dynamics of viscoelastic jets composed of carboxymethyl cellulose (CMC) solutions, focusing on the dripping and Rayleigh regimes at low fl…
Droplet breakup morphologies and the resultant size distribution in an opposed-flow airstream at different Weber numbers
Shubham Chakraborty, Someshwar Sanjay Ade, Lakshmana Dora Chandrala +1
The present study investigates the morphology and breakup dynamics of a freely falling drop in a vertical airstream using shadowgraphy and in-line holography. The in-line holograph…
An Investigation of Flow and Interface Dynamics Near a Moving Contact Line at Obtuse Contact Angles
Charul Gupta, Venkata Sai Anvesh Sangadi, Lakshmana Dora Chandrala +1
The flow near a moving contact line is primarily governed by three key parameters: viscosity ratio, dynamic contact angle, and inertia. While the behavior of dynamic contact angles…
Drop size distribution from laboratory experiments based on single-drop fragmentation and comparison with aerial in-situ measurements
Shubham Chakraborty, Someshwar Sanjay Ade, Lalsingh Devsoth +4
Laboratory experiments and theoretical modelling are conducted to determine the raindrop size distribution (DSD) resulting from distinct fragmentation processes under various upwar…
Droplet breakup and size distribution in an airstream -- effect of inertia
Someshwar Sanjay Ade, Pavan Kumar Kirar, Lakshmana Dora Chandrala +1
We experimentally investigate the morphology and breakup of a droplet as it descends freely from a height and encounters an airstream. The size distributions of the child droplets…
Application of deep learning and inline holography to estimate the droplet size distribution
Someshwar Sanjay Ade, Deepa Gupta, Lakshmana Dora Chandrala +1
We examine five machine learning-based architectures to estimate the droplet size distributions obtained using digital inline holography. The architectures, namely, U-Net, R2 U-Net…
An experimental investigation of flow fields near a liquid-liquid moving contact line
Charul Gupta, Lakshmana D Chandrala, Harish N Dixit
A moving contact line occurs at the intersection of an interface formed between two immiscible liquids and a solid. According to viscous theory, the flow is entirely governed by ju…
An experimental study of flow near an advancing contact line: a rigorous test of theoretical models
Charul Gupta, Anjishnu Choudhury, Lakshmana D Chandrala +1
The flow near a moving contact line depends on the dynamic contact angle, viscosity ratio, and capillary number. We report experiments involving immersing a plate into a liquid bat…
Size distribution of a drop undergoing breakup at moderate Weber numbers
Someshwar Sanjay Ade, Lakshmana Dora Chandrala, Kirti Chandra Sahu
