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…
