Abstract The linear spatiotemporal stability properties of axisymmetric laminar capillary jets with fully developed initial velocity profiles are studied for large values of both the Reynolds number, $\mathit{Re}= Q/ (\lrm{\pi} a\nu )$, and the Froude number, $\mathit{Fr}= {Q}^{2} / ({\lrm{\pi} }^{2} g{a}^{5} )$, where $a$ is the injector radius, $Q$ the volume flow rate, $\nu $ the kinematic viscosity and $g$ the gravitational acceleration. The downstream development of the basic flow and its… 

The nonlinear states of viscous capillary jets confined in the axial direction

We report an experimental and theoretical study of the global stability and nonlinear dynamics of vertical jets of viscous liquid confined in the axial direction due to their impact on a bath of the

Viscoelastic liquid curtains: experimental results on the flow of a falling sheet of polymer solution

We experimentally investigate the extensional flow of a sheet – or curtain – of viscoelastic liquid falling freely from a slot at constant flow rate under gravity. Extruded liquids are aqueous

The structure of the absolutely unstable regions in the near field of low-density jets

Abstract The viscous spatiotemporal stability properties of low-density laminar round jets emerging from circular nozzles or tubes are investigated numerically providing, for the first time, a

Global stability and nonlinear dynamics of wake flows with a two-fluid interface

Abstract A framework for the computation of linear global modes, based on time stepping of a linearised Navier–Stokes solver with an Eulerian interface representation, is presented. The method is

Frequency selection in a gravitationally stretched capillary jet in the jetting regime

A capillary jet falling under the effect of gravity continuously stretches while thinning downstream. We report here the effect of external periodic forcing on such a spatially varying jet in the

Torricelli's curtain: Morphology of horizontal laminar jets under gravity

Viscous fluid exiting a long horizontal circular pipe develops a complex structure comprising a primary jet above and a smaller secondary jet below with a thin fluid curtain connecting them. We

Stretching liquid flows: jets, drops and liquid bridges. Experiments and one-dimensional modelling of linear and non-linear phenomena in laminar capillary flows

The present PhD Thesis deals with several linear and nonlinear phenomena present in extensional laminar capillary flows, such as jets, drops and liquid bridges. When dispensing liquid from a vertical

A simple hydrodynamic model of a laminar free-surface jet in horizontal or vertical flight

A useable model for laminar free-surface jet evolution during flight, for both horizontal and vertical jets, is developed through joint analytical, experimental, and simulation methods. The jet’s

Spatial modes of capillary jets, with application to surface stimulation

Abstract Surface stimulation of any physical origin (electrohydrodynamic, thermocapillary, etc.) has the goal of generating localized perturbations on the free surface or the velocity field of a

Paradoxical predictions of liquid curtains with surface tension

Abstract This paper examines two-dimensional liquid curtains ejected at an angle to the horizontal and affected by gravity and surface tension. The flow is, to leading order, shearless and viscosity,



Aerodynamic effects in the break-up of liquid jets: on the first wind-induced break-up regime

We present both numerical and analytical results from a spatial stability analysis of the coupled gas–liquid hydrodynamic equations governing the first wind-induced (FWI) liquid-jet break-up regime.

Linear stability of co-flowing liquid–gas jets

A temporal, inviscid, linear stability analysis of a liquid jet and the co-flowing gas stream surrounding the jet has been performed. The basic liquid and gas velocity profiles have been computed

The stability problem for a thin film of liquid having a linear mean-velocity profile and bounded by a fixed wall and free surface is solved asymptotically for large values of the Reynolds number R.

Nonlinear dynamics and breakup of free-surface flows

Surface-tension-driven flows and, in particular, their tendency to decay spontaneously into drops have long fascinated naturalists, the earliest systematic experiments dating back to the beginning of


The goal of this survey is to review recent developments in the hydro­ dynamic stability theory of spatially developing flows pertaining to absolute/convective and local/global instability concepts.

This paper is concerned with the jet of liquid, open to the atmosphere, that emerges from a two-dimensional channel in which there is Poiseuille flow far upstream, the flow being driven by an applied

Computational and experimental analysis of dynamics of drop formation

Dynamics of formation of a drop of a Newtonian liquid from a capillary tube into an ambient gas phase is studied computationally and experimentally. While this problem has previously been studied

Absolute and convective instability of a relaxational plane liquid jet

The stability of a plane relaxational liquid jet has been studied theoretically and experimentally through linear stability analysis and flow visualizations. The relaxational liquid jet is obtained

Generation and breakup of Worthington jets after cavity collapse. Part 2. Tip breakup of stretched jets

The capillary breakup of the high-speed Worthington jets ejected after a cavity collapse in water occurs due to the high-Reynolds-number version of the capillary end-pinching mechanism first


The objective of this review is to critically assess the different approaches developed in recent years to understand the dynamics of open flows such as mixing layers, jets, wakes, separation
