The study on the Deep Ocean Water Discharge Technology Using a Numerical Simulation

Abstract

Recently, the deep ocean water is drawing attention as a recyclable resource.
The author made models explain relations between methods on discharging of the deep ocean water and enrich shallow sea using a numerical simulation as an experiment. The author used a 3-D general-purpose heat flow analysis program for calculation of these models. The behavior of the discharge plume was observed with method of tracing particles. The author tried to evaluate quantitatively the difference among discharge methods, the seabottom shape, influence of subsurface structure and several factors including the distribution of salinity. In this study, 6 cases of discharging into stilling basin were calculated. This calculation was carried out without taking any forcing except for the buoyancy into consideration to simplify it.
The study on the behavior of the plume under various forces is a future subject.
