Spatiotemporal structure of hydrothermal waves in Marangoni convection

AB Ezersky, A Garcimartin, HL Mancini, C Perez-Garcia - Physical Review E, 1993 - APS
When a liquid layer is laterally heated, the basic flow loses stability in the form of
hydrothermal waves. They can be visualized by means of the shadowgraph technique. The …

Instabilities by local heating below an interface

G Gouesbet, C Rozé, S Meunier-Guttin-Cluzel - 2001 - degruyter.com
Thermal lens oscillations, and associated hot-wire experiments, pertain to a class of
instabilities produced when the free surface of a liquid is locally heated from below …

Primary instabilities in convective cells due to nonuniform heating

AM Mancho, H Herrero, J Burguete - Physical Review E, 1997 - APS
We study a convection problem in a container with a surface open to the air and heated by a
long wire placed at the bottom. Coupled buoyancy and thermocapillarity effects are taken …

Centrifugal instabilities in an experimental open cavity flow

CL Douay, LR Pastur, F Lusseyran - Journal of Fluid Mechanics, 2016 - cambridge.org
We present an experimental parametric study of spanwise centrifugal instabilities in an open
cavity flow. We show that the mode selected at threshold depends on the cavity streamwise …

Influence of aspect ratio in convection due to nonuniform heating

H Herrero, AM Mancho - Physical Review E, 1998 - APS
The influence of fluid depth in a convection problem in which heating is nonuniform is
studied. We consider a vessel that has at the bottom a temperature distribution which has …

Experimentally observed route to spatiotemporal chaos in an extended one-dimensional array of convective oscillators

MA Miranda, J Burguete - Physical Review E—Statistical, Nonlinear, and Soft …, 2009 - APS
We report experimental evidence of the route to spatiotemporal chaos in a large one-
dimensional array of hotspots in a thermoconvective system. As the driving force is …

Subcritical instabilities in a convective fluid layer under a quasi-one-dimensional heating

MA Miranda, J Burguete - Physical Review E—Statistical, Nonlinear, and Soft …, 2008 - APS
The study and characterization of the diversity of spatiotemporal patterns generated when a
rectangular layer of fluid is locally heated beneath its free surface is presented. We focus on …

One-dimensional dynamics in locally heated liquid layers

J Burguete, D Maza, HL Mancini - Physica D: Nonlinear Phenomena, 2003 - Elsevier
Recent results on one-dimensional patterns in locally heated experiments are presented. A
fluid layer is heated locally by a nearly one-dimensional heater, and subjected to both …

Localized structures in convective experiments

J Burguete, H Mancini - The European Physical Journal Special Topics, 2014 - Springer
In this work we review localized structures appearing in thermo-convective experiments
performed in extended (large “aspect ratio”) fluid layers. After a brief general review (not …

Exploring the Kibble–Zurek mechanism in a secondary bifurcation

MA Miranda, J Burguete… - … Journal of Bifurcation …, 2012 - World Scientific
We present new experimental results on the quenching dynamics of an extended thermo-
convective system (a network array of approximately 100 convective oscillators) going …
