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…
A Robust Truncated-Domain Approach for Cone--Jet Simulations in Electrospinning and Electrospraying
Ghanashyam K. C., Satyavrata Samavedi, Harish N Dixit
Direct numerical simulations of electrospinning and electrospraying are computationally demanding due to large-scale separation between the needle and the tip-to-collector distance…
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…
