Viscosity and dynamic surface tension measurement: A guideline for appropriate measurement
Vivek Kumar, JSM Quintero, Aleksey Baldygin +3
Dynamic surface tension measurements play a critical role in interfacial activities for liquids with varying viscosities. Understanding the rate at which the interface attains the…
Drop spreading dynamics with a liquid needle drop deposition technique
Abrar Ahmed, Anuvrat Mishra, MD Farhad Ismail +3
This paper represents a theoretical and an experimental study of the spreading dynamics of a liquid droplet, generated by a needle free deposition system called the liquid needle d…
Universality in the initial electrocoalescence
Juan S. Marin Quintero, Markus Cäsar, Prashant R. Waghmare
The characteristic time for the electrocoalescence of two sessile drops is identified and verified for wide range of operating parameters such as Ohnesorge, Electrowetting number,…
Double emulsion drop evaporation and resurfacing of daughter droplet
Muhammad Rizwanur Rahman, Prashant R. Waghmare
In this study, we present experimental and theoretical analyses of double emulsion drop evaporation. After the apparent completion of evaporation of the inner phase of a double emu…
Inertial Rise in Short Capillaries
Orest Shardt, Prashant R. Waghmare, J. J. Derksen +1
In this fluid dynamics video we show capillary rise experiments with diethyl ether in short tubes. The height of each short tube is less than the maximum height the liquid can achi…
