Journal ArticleDOI
Two-valued breakup length of a water jet issuing from a finite-length nozzle under normal gravity.
TL;DR: The previously proposed self-destabilizing mechanism of a liquid jet in microgravity, in which the origin of the unstable wave responsible for the breakups is attributed to the formation of an upstream propagating capillary wave at every breakup, is extended to explore the physics underlying the observed liquid jet disintegration behaviors.
Journal ArticleDOI
Self-destabilizing loop observed in a jetting-to-dripping transition
Akira Umemura,Jun Osaka +1 more
TL;DR: In this paper, the authors used high-speed camera images to identify the origin of the Plateau-Rayleigh unstable wave elements which disintegrate the jetting liquid and showed that these processes are repeatable and constitute a self-destabilizing loop.
Journal ArticleDOI
A study on single fuel droplets combustion in vertical direct current electric fields
TL;DR: In this paper, the authors investigated the combustion behavior of single droplets in vertical direct current electric fields and found that when the direction of the electric field is opposite to the natural buoyancy direction, the applied voltage exists that make the flame symmetrical in the vertical direction.
Journal ArticleDOI
Influences of Uniform Electrical Fields on Burning Rate Constant of Ethanol Droplet Combustion
TL;DR: In this paper, the burning rate constants of ethanol droplet flame under uniform electrical fields were investigated experimentally and numerically, and a two-dimensional numerical simulation was also conducted on the droplet combustion in a uniform electrical field.
Journal ArticleDOI
Observation of sooting behavior in single droplets combustion in direct current electric fields under microgravity
TL;DR: In this paper, the authors focused on movement of soot particle in single droplets combustion in direct current electric fields under microgravity in order to obtain some information about flow field around droplet.
