Sand liquefaction has been generated by horizontal vibration of a sand-liquid mixture. The pattern
formation of the sand-liquid interface was found at large vibration intensity.
The vibro-convective nature of this
relief generation is proved. We demonstrate that the only controlling
parameter is
(radian frequency
, amplitude b, cell diameter D, gravity g). An analogy
is made with
the vibro-convective relief generation of
the interface between two immiscible liquids in a closed cell
submitted to high-frequency horizontal
vibration. Hence, most of the results are similar to those obtained with a liquid-liquid
interface as shown in this paper;
nevertheless we emphasize some peculiarities of sand behavior.
