摘要
A type of port with a movable cover is designed to increase initial dilution and prevent sea water and sediments from intruding into outfall systems.Horizontal radial jets pro- duced by this type of port in a current are investigated experimentally and theoretically.The analysis based on Reynolds'equations and self-similarity hypothesis shows that the maximum ve- locity of radial jets decays with r^(-1.5).The relationships between the width,thickness,average di- lution of a submerged wastefield along flow,and the parameters of the port,jet and ambient are established quantitatively and verified by experiments.It is demonstrated that the dilution of horizontal radial jets is much higher than that of vertical round jets and the surface boil point of the former is much more distant than that of the latter.
