Abstract
The invention relates to apparatus for making waves in a liquid in test tanks and the like by the back and forth movement in the liquid of a displacer. A problem caused by the escape of liquid round the side of the displacer during such movement is overcome by the provision of a seal between the displacer and the wall of the tank, which seal by a rolling action allows relative movement between the wall and the displacer.
Claims5
Apparatus for making waves in a body of liquid comprising a container for the liquid, including a longitudinal dimension and opposed inner surfaces spaced apart transversely, displacing means having an active face disposed substantially transversely between said inner surfaces, said active face having opposed sides means for moving said displacing means longitudinally back and forth in said container between said opposed inner surfaces, so that said active face, in motion, creates a wave-pattern in the liquid, and further including flexible seal means between said sides and said opposed inner surfaces, to prevent liquid from flowing between said sides and said corresponding inner surfaces.
