Geometric Dynamics of Turbulence: A Minimal Oscillator Structure from Non-local Closure
Alejandro Sevilla
Turbulence remains one of the central open problems in classical physics, largely due to the absence of a closed dynamical description of the Reynolds stress. Existing approaches t…
The influence of an outer bath on the dewetting of an ultrathin liquid film
A. Martinez-Calvo, D. Moreno-Boza, J. F. Guil-Pedrosa +1
We report a theoretical and numerical investigation of the linear and nonlinear dynamics of a thin liquid film of viscosity sandwiched between a solid substrate and an unbounde…
Universal Free-Fall Law for Liquid Jets under Fully Developed Injection Conditions
M. Beneitez, D. Moreno-Boza, A. Sevilla
We show that vertical slender jets of liquid injected in air with a fully-developed outlet velocity profile have a universal shape in the common case in which the viscous force is…
Linear stability of ultrathin spherical coatings
D. Moreno-Boza, A. Sevilla
We unravel the linear stability properties of an otherwise stagnant ultrathin non-wetting liquid film of thickness coating a spherical substrate of radius . The configurat…
Non-axisymmetric modes in ultrathin annular liquid films coating a cylindrical fibre
D. Moreno-Boza, A. Sevilla
This paper presents a detailed analysis of the three-dimensional stability properties of an annular liquid film coating a cylindrical fibre in the presence of van der Waals (vdW) i…
Axisymmetric bubble pinch-off at high Reynolds numbers
José Manuel Gordillo, Alejandro Sevilla, Javier Rodríguez-Rodríguez +1
Analytical considerations and potential flow numerical simulations of the pinch-off of bubbles at high Reynolds numbers reveal that the bubble minimum radius, , decreases as $…
On the flow separation mechanism in the inverse Leidenfrost regime
J. Arrieta, A. Sevilla
The inverse Leidenfrost regime occurs when a heated object in relative motion with a liquid is surrounded by a stable vapour layer, drastically reducing the hydrodynamic drag at la…
Stokes theory of thin-film rupture
D. Moreno-Boza, A. Martínez-Calvo, A. Sevilla
The structure of the flow induced by the van der Waals destabilization of a non-wetting liquid film placed on a solid substrate is unraveled by means of theory and numerical simula…
Natural break-up and satellite formation regimes of surfactant-laden liquid threads
A. Martínez-Calvo, J. Rivero-Rodríguez, B. Scheid +1
We report a numerical analysis of the unforced break-up of free cylindrical threads of viscous Newtonian liquid whose interface is coated with insoluble surfactants, focusing on th…
The nonlinear states of viscous capillary jets confined in the axial direction
A. Martínez-Calvo, M. Rubio-Rubio, A. Sevilla
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 impac…
Global instability of low-density jets
W. Coenen, L. Lesshafft, X. Garnaud +1
The global stability of laminar axisymmetric low-density jets is investigated in the low Mach number approximation. The linear modal dynamics is found to be characterised by two fe…
Global stability of stretched jets: conditions for the generation of monodisperse micro-emulsions using coflows
José Manuel Gordillo, Alejandro Sevilla, Francisco Campo-Cortés
In this paper we reveal the physics underlying the conditions needed for the generation of emulsions composed of uniformly sized drops of micrometric or submicrometric diameters wh…
