Autor: Alfonso M. Gañán-Calvo, Henry N. Chapman, Michael Heymann, Max O. Wiedorn, Juraj Knoska, Braulio Gañán-Riesco, José M. López-Herrera, Francisco Cruz-Mazo, Miguel A. Herrada, José M. Montanero, Saša Bajt
Publikováno v: Crystals, Vol 11, Iss 8, p 990 (2021)
One of the most successful ways to introduce samples in Serial Femtosecond Crystallography has been the use of microscopic capillary liquid jets produced by gas flow focusing, whose length-to-diameter ratio and velocity are essential to fulfill the r

Beware of CaBER: Filament thinning rheometry does not always give `the' relaxation time of polymer solutions
Autor: Gaillard, Antoine, Gutierrez, Miguel Angel Herrada, Deblais, Antoine, Eggers, Jens, Bonn, Daniel
The viscoelastic relaxation time of a polymer solution is often measured using Capillary Breakup Extensional Rheometry (CaBER) where a droplet is placed between two plates which are pulled apart to form a thinning filament. For a slow plate retractio

Global stability analysis of bubbles rising in a vertical capillary with an external flow
Autor: Miguel A. Herrada, Yingxian Estella Yu, Howard A. Stone
Publikováno v: Journal of Fluid Mechanics. 958
We study the linear stability of bubbles in a capillary tube under external flow. Yu et al. (J. Fluid Mech., vol. 911, 2021, pp. 1–19) showed that a rich variety of bubble dynamics occurs when a downward external flow is applied, opposing the buoya

Path instability of an air bubble rising in water
Autor: Miguel A. Herrada, Jens G. Eggers
Publikováno v: Proceedings of the National Academy of Sciences. 120
It has been documented since the Renaissance that an air bubble rising in water will deviate from its straight, steady path to perform a periodic zigzag or spiral motion once the bubble is above a critical size. Yet, unsteady bubble rise has resisted

Elastic Rayleigh–Plateau instability: dynamical selection of nonlinear states
Autor: Anupam Pandey, Jens Eggers, Jacco H. Snoeijer, Miguel A. Herrada, Minkush Kansal

Pandey, A, Kansal, M, Herrada, M A, Eggers, J G & Snoeijer, J H 2021, ' Elastic Rayleigh-Plateau instability : Dynamical selection of nonlinear states ', Soft Matter, vol. 17, no. 20, pp. 5148-5161 . https://doi.org/10.1039/D0SM02195D
A slender thread of elastic hydrogel is susceptible to a surface instability that is reminiscent of the classical Rayleigh-Plateau instability of liquid jets. The final, highly nonlinear states that are observed in experiments arise from a competitio

A method for measuring the interfacial tension for density-matched liquids
Autor: Miguel A. Herrada, B.N. Muñoz-Sánchez, M. G. Cabezas, José María Montanero, C. Ferrera
Publikováno v: Journal of Colloid and Interface Science. 566:90-97
We propose a method to measure the interfacial tension characterizing the interface between two immiscible liquids of practically the same density. In this method, a cylindrical liquid bridge made of one the liquids is vibrated laterally inside a tan

Mechanism of Disappearance of Vortex Breakdown in a Confined Flow
Autor: Vladimir Shtern, Miguel A. Herrada, B. R. Sharifullin, Luis Carrión, Igor V. Naumov
Publikováno v: Journal of Engineering Thermophysics. 29:49-66
This experimental and numerical work explains why a vortex breakdown bubble first emerges and then disappears as the fluid rotation speeds up. To this end, we explore a flow in a sealed cylindrical container with one end disk rotating and all other w

We consider the stability of flux-driven flow through a long planar rigid channel, where a segment of one wall is replaced by a pre-tensioned hyperelastic (neo-Hookean) solid of finite thickness and subject to a uniform external pressure. We construc
