Local Marangoni number at the onset of hydrothermal waves
MA Pelacho, A Garcimartin, J Burguete - Physical Review E, 2000 - APS
We report the results of an experiment in which a layer of fluid, placed in a container open to
the air, is subjected to a horizontal temperature difference Δ T. The fluid height h is kept
constant and both the horizontal temperature difference and the horizontal dimensions of the
fluid layer are changed. In this configuration, when Δ T goes beyond a certain threshold,
waves propagating from the cold to the hot side appear (hydrothermal waves) with a
determined group velocity. We study the influence of the container geometry on these …

We report the results of an experiment in which a layer of fluid, placed in a container open to
the air, is subjected to a horizontal temperature difference DT. The fluid height h is kept
constant and both the horizontal temperature difference and the horizontal dimensions of the
