Abstract

The apparatus is used to produce circular or plane waves, using pulses of compressed air. For circular waves, it comprises a block (1) supporting one or more tubes (2, 3). These are elongated horizontally (6, 7) and terminate vertically (8, 9), their open ends pointing downwards and just above the liquid surface. The pulses are supplied from a diaphragm pump and regulated by valves (4, 5). For plane waves, the pulses are fed into a horizontal tube and into a chamber formed by a channel section, its open end submerged in the liquid. The internal pressure pulses propagate external waves.
