Influence of boundary conditions on 2-fluid Systems under horizontal vibration

TL;DR

This study investigates how boundary conditions and cell shape influence pattern formation in 2-phase systems subjected to horizontal vibration under gravity, revealing high sensitivity to experimental parameters.

Contribution

It demonstrates the significant impact of boundary conditions, cell shape, and vibration mode on pattern formation in vibrated 2-fluid systems under gravity.

Findings

Patterns are highly sensitive to cell shape and boundary conditions.

Vibration mode and direction significantly influence pattern types.

Boundary effects are crucial in 2-fluid vibrated systems.

Abstract

This paper is concerned with 2-phase systems under vibration in gravity condition, when the gravity is perpendicular to the direction of vibration. It tries and demonstrates that, even in such a restricted case, the patterns which can be formed are very sensitive to the cell shape, to the boundary conditions and to the direction and the mode of vibration, i.e. linear, rotational,...
