Atomization of an Undulating Liquid Sheet

This paper presents an experimental study devoted to the understanding of break-up mechanisms of liquid sheets. A shear instability develops at the interface liquid/gas resulting in an undulated motion of the liquid sheet. These undulations trig a Rayleigh-Taylor instability leading to azimuthal thickness modulations. A model including the development of both instabilities allows us to predict ...

an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols

this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...

Wettability of Liquid Tin on Solid Copper* By

For obtaining good joints by soldering, a wettability of liquid metal on the solid metal surface, relatlatte, relattlated o solderability, is one of the most important factors, and the wettability is accelerated by using a suitable flux and atmosphere. In atmosphere soldering the flow of molten solder will be retarded by oxide films on base metals formed by a small amount of oxygen in atmospher...

Stability of liquid sheet edges

Accelerating edges of thin liquid sheets are ubiquitous and are known to experience a longitudinal along-the-edge instability, which often leads to their break-up and atomization. The fundamental physical mechanisms of this instability are studied analytically in the quasisteady regime, which admits a concise modeling. It is discovered that the classical Rayleigh–Taylor mechanism is substantial...
