Six flow modes are distinguished in the flow-focusing experiments of a liquid jet forced by a
high-speed air stream. The domains of the modes are identified on the parameter space of …

We adress the question of the stability of a confined coflowing jet at low Reynolds number in
various geometries. Our study is motivated by recent experiments in microfluidic devices …

We consider the temporal instability of parallel two-phase mixing layers. The viscous case is
examined using a composite error-function velocity profile. The inviscid case is considered …

In the framework of linear stability theory, we analyze how a liquid-gas mixing layer is
affected by several parameters: viscosity ratio, density ratio, and several length scales …

In the present work we study the large-scale helical vortex shedding regime in the wake of
an axisymmetric body with a blunt trailing edge at high Reynolds numbers, both …

Recent experimental studies on the instability of capillary jets have revealed the suitability of
a linear spatiotemporal instability analysis to ascertain the parametrical conditions for …

流动聚焦是一种有效的微细射流产生方法, 其原理可以描述为从毛细管流出的流体由另一种高速

This study investigates the stability features of spatially spreading heated jets in the viscous
regime with real gas effects, using both unsteady two-dimensional axisymmetric simulations …

Experiments were performed on the deformation and breakup of annular liquid sheet of nine
coaxial twin-fluid air-blast atomizers with water–air systems by using a high speed camera …

A laminar inviscid liquid (typically water) jet issuing from a circular nozzle into otherwise
quiescent air disintegrates into droplets periodically at a distance from the nozzle. The …
