Flow measurements in the wake of an adhering and oscillating droplet using laser-Doppler velocity profile sensor [PDF]
Experiments in Fluids, 2021 AbstractThe removal of droplets on surfaces by an (air-) flow is relevant, e.g., for cleaning processes or to prevent corrosion or damage of electronic devices. Still the condition for droplet movement is not fully understood. Droplets start to move downstream at a critical (air-) flow velocity vcrit.

Numerical study of continuous liquid tin jet breakup and satellite droplet formation
AIP Advances, 2022 This study proposed a velocity modulation model in which the main flow and perturbation were defined as velocity inlet boundary conditions to simulate liquid tin jet breakup into droplets with external disturbances.

Velocity Profile inside Piezoacoustic Inkjet Droplets in Flight: Comparison between Experiment and Numerical Simulation [PDF]
Physical Review Applied, 2014 Inkjet printing deposits droplets with a well-controlled narrow size distribution. This paper aims at improving experimental and numerical methods for the optimization of drop formation. We introduce a method to extract the one-dimensional velocity profile inside a single droplet during drop formation.

Probabilistic derivation of droplet velocity using quadrature method of moments
Open Engineering, 2023 Accurately prediction of dispersion and polydispersity of droplet flow is not a trivial task due to the complex behavior of the droplet size distribution (DSD) and the strong state of the instantaneous velocity of a droplet on the shape and size of the ...

Numerical study of droplet formation in the T-junction microchannel with wall velocity slip
Energy Procedia, 2019 Effect of hydrophobicity on droplet formation in the T-junction microfluidic devices is numerically studied. A Navier slip model is adopted. Results reveal that, as increasing of slip length, the velocity profile across the channel becomes flattened ...
