Structure and dynamics of a bidimensional pattern of liquid columns

Structure and dynamics of a bidimensional pattern of liquid columns We report an experimental study of the structure and dynamics of a bidimensional array of liquid columns. This pattern is formed below a flat porous plate continuously supplied with liquid. It exhibits a marked hexagonal tendency. Its typical wavelength is close to that of the most dangerous mode of the Rayleigh–Taylor instability of a thin viscous layer hanging below a plate, defined by the competition between gravity and surface tension. Collective dynamical behaviors are also evidenced, involving oscillations of the column positions, columns migrations, coalescences and nucleations. Quantitative comparisons are presented with the equivalent one-dimensional pattern formed below the perimeter of an overflowing dish (“circular fountain experiment”). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

We report an experimental study of the structure and dynamics of a bidimensional array of liquid columns. This pattern is formed below a flat porous plate continuously supplied with liquid. It exhibits a marked hexagonal tendency. Its typical wavelength is close to that of the most dangerous mode of the Rayleigh–Taylor instability of a thin viscous layer hanging below a plate, defined by the competition between gravity and surface tension. Collective dynamical behaviors are also evidenced, involving oscillations of the column positions, columns migrations, coalescences and nucleations. Quantitative comparisons are presented with the equivalent one-dimensional pattern formed below the perimeter of an overflowing dish (“circular fountain experiment”).
