AN ANALYSIS OF THE FLUID MOTION INTO THE CONDENSER INTAKE OF A 400 MW(E) OCEAN THERMAL DIFFERENCE POWER PLANT

摘要

The report addresses the following questions regarding the operation of an intake device in a complex stratified flow typical of the Gulf Stream: (1) would flow into such an intake create disruption of the thermocline if placed in depths of the order of 300-800 meters thereby withdrawing warm surface waters which would adversely affect the condenser operation, (2) if a finite withdrawal layer is created by such a device, what is the size and configuration of that layer as a function of ambient conditions (density stratification and current speed), intake operating characteristics (principally flow rate) and intake geometry (diameter and depth of intake), (3) what is the effect of such a withdrawal layer on the average temperature of the water so withdrawn, and can this average temperature by predicted, (4) what is the possibility of entraining botton deposits from such an intake device and can some criteria be developed for avoiding scouring.
