WAVE EXTINCTION BY PNEUMATIC BREADWATER

Abstract

Pneumatic wave extinguishers for the protection of port constructions are discussed. For better utilization of the wave extinguishers it is necessary to establish the mechanism of the wave extinction process by air-bubbles. The basic causes of extinction are: (1) wave extinction by the speed (velocity) field superimposed on it, created by the motion of the bubbles; (2) reflection of the wave from the curtain of bubbles; and (3) loss of energy on shrinkage and expansion of the rising bubbles of air while passing the crest and trough of the wave above them. The present study was primarily the examination of wave extinction due to circulation currents and turbulence.
