Abstract
Combined Optical Connectivity and Optical Flow Velocimetry for interfacial characterisation of liquid atomisation
Highlights
Atomisation disintegrates a continuous liquid fragment into fine droplets by external deformation due to shear and is important for many applications, including liquid fuel combustors, medical spraying or industrial coating
The instantaneous optical connectivity (OC) fluorescent intensity images show that increased intensity is recorded at locations where evident deformations are formed at the liquid surface, which assists the tracking of the wavy structure of the liquid surface
The paper presented the interfacial characteristics of a liquid jet injected into quiescent air with different flow velocity
Summary
Atomisation disintegrates a continuous liquid fragment into fine droplets by external deformation due to shear and is important for many applications, including liquid fuel combustors, medical spraying or industrial coating. For case free of aerodynamic effect, Umemura [15] found that the deformation of the jet surface could be due to an instability of the thin liquid shear layer flow, which relaxes the liquid velocity profile produced by the nozzle wall.
