Interaction of Surface Waves and a Jet
ABSTRAKT
Experimental results from the imposition of gravity waves upon a submerged turbulent jet are presented. Velocity and turbulence correlations between gravity wave parameters and turbulent jet characteristics are determined.
LDA measurements of the waves show that the location of highest turbulence occurs below the wave trough. The characteristics of the turbulent jet are directly affected by the imposed wave power. For low wave powers (less than 10 N/s) a power increase affects the jet in a similar manner as raising the jet Reynolds number. For wave powers of greater than 9 N/s, a power increase raises the jet dilution. The jet velocity profiles, which are not skewed by the waves, remain Gaussian under the wave effects. The turbulence profiles are skewed and shifted towards the water surface in accordance with the wave power. It is shown that gravity waves increase the dilution achieved by turbulent jets.
