Circulation flow patterns in the Faraday waves in the presence of damper plates

Resumo

The effect of transverse damper plates on the restructurization of a suspension with originally homogeneous concentration in the field of standing surface waves in a vertically oscillating rectangular reservoir is for the first time experimentally investigated. The flow pattern evolution and the formation of the fine flow structure are traced in reservoirs with smooth walls, with one vertical deflecting plate, and with two plates mounted in parallel or antiparallel at the center of the larger side. The symmetry of the surface wave flow is determined by the plate configuration.
