Abstract
In order to make practical use of the deep sea-water (DSW) on commercial base, it is desired to have a large quantity of DSW for many purposes, especially for using its energy resource. For example, in case of using DSW for cooling a power plant of 600mega-wat, the required volume of DSW is estimated as large as 1, 000, 000 m3 per day. When such large quantity of DSW is discharged to the coastal sea area, it is necessary to study how to discharge DSW with a minimum damage to the ecosystem or even with giving positive influence (s).
The swirl flow discharge head was then proposed for discharging such a large quantity of DSW, and its basic character was evaluated by the experiments in the present study.
