Abstract

Threshold for Faraday instability has been experimentally measured for slightly viscous liquids. Changing the size of the container containing the fluid allows us to emphasize the role played by the capillary meniscus on the onset for instability. As the container is getting smaller, an upset of the critical acceleration is observed. Below a given container diameter, eigenmodes are observed along the stability curve. A dissipation term is proposed for considering the viscous dissipation against the walls of the container.
