| Abstract | This work describes the use of mixing tubes in sewage disposal
from marine outfalls. The mixing tube placed in front of the outlet
at the sewage outfall (outlet serving as nozzle) constitutes a water jet-pump system. The characteristics of such a system are governed by the ratio of nozzle to mixing tube diameters. The theoretical values of dilutions are calculated by using this ratio and knowledge of the
diffusion of submerged jets in ambient water of higher density. Higher dilutions were obtained in the experimental study than by the above procedure. This was attributed to the turbulence generated by the action of jet-pump over and above that of the simple submerged jet.
Amplification factors are supplied for determining the dilution, to be calculated by the theory for a range of diameter ratios, nozzle Froude numbers and depth to nozzle diameter ratios. It is concluded that
the mixing tube provides advantages over the simple submerged jet for small discharge depths for diameter ratios of less than % and Froude
number from 150 to 800. |
