THE SPECTRAL CHARACTER OF ACOUSTIC WAVES RADIATED BY A WATERHAMMER-EXCITED CYLINDRICAL DIAPHRAGM

An experimental model, designed to study the effects of geometry and flow conditions on wave patterns, found one major wave originating from the primary water hammer compressive wave downstream from the diamphragm and the other major wave originiating upstream of the diaphragm. Computation of the energy distributions for different experimental conditions indicated that a concentration of energy in the lower frequency zone is favored by high flow velocity, large pipe diameter, and long lengths of rigid pipe downstream from the diaphragm.
