An Experimental Study of Plunging Liquid Jet Induced Air Carryunder and Dispersion
Abstract
A good understanding of the air carryunder and bubble dispersion process associated with a plunging liquid jet is vital if one is to be able to quantify such diverse phenomena as the environmental impact of power plant discharges, sea surface chemistry, the meteorological significance of (Breaking) ocean waves, the performance of certain type of chemical reactors, the 'greenhouse' effect (ie, the absorption of CO2 by the oceans), and a number of other important maritime-related applications. In particular, the air entrainment process due to the breaking bow waves of surface ships may cause long (ie, up to 5 km in length) wakes. Naturally easily detectable wakes are undesirable for naval warships. In the present study plunging liquid jet experiments were performed and detailed Laser Doppler Anemometer (LDA) data were taken of the phasic velocity field and the void fraction distribution in the induced two-phase jet.
