The Approximate Theories of Pneumatic Wave Generators: Hydraulic Laboratory Investigation

Abstract

After a brief discussion of the genesis of oscillatory waves by the pneumatic method, the required pressure condition for the genesis of long surges with constant wave heights is discussed. Reasoning from the energy point of view, it is seen that the sum of the pressure head in the pneumatic chamber and the water elevation therein should remain constant during the issuance of the wave from the generator. Procedures for the design of a pneumatic generator for long waves are outlined and are applied for the generator used in the Hilo Harbor model used to study the problems of protection against tsunamis.
