\textbf{Surfactant effects in dynamics and breakup of a contracting liquid filament}
Qi Xu,Osman A. Basaran +1 more
Journal ArticleDOI
Computational analysis of drop-on-demand drop formation
Qi Xu,Osman A. Basaran +1 more
TL;DR: In this article, the formation of liquid drops of incompressible Newtonian fluids from a simple capillary tube by imposing a transient flow rate upstream of the nozzle exit is studied.
Journal ArticleDOI
Analysis of the drop weight method
TL;DR: The drop weight method is an accurate yet simple technique for determining surface tension σ as mentioned in this paper, which relies on dripping a liquid of density ρ at a low flow rate Q from a capillary of radius R into air and measuring the combined volumes of the primary and satellite drops that are formed.
Journal ArticleDOI
Simplicity and complexity in a dripping faucet
Hariprasad J. Subramani,Hak Koon Yeoh,Ronald Suryo,Qi Xu,Bala Ambravaneswaran,Osman A. Basaran +5 more
TL;DR: In this article, the effect of the governing parameters on the nonlinear dynamics of a leaky faucet was studied by a combination of experiment, using high-speed imaging, and computation, in which the one-dimensional slender-jet equations are solved numerically by finite element analysis, over ranges of governing parameters that have heretofore been unexplored.
Journal ArticleDOI
Can surfactant be present at pinch-off of a liquid filament?
TL;DR: Here theory and simulation are used to investigate pinch-off of microscopic filaments and two such regimes with distinct dynamics characterized by different scaling exponents are reported.
