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…
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…
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…
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…
