Circulation Induced by Coastal Diffuser Discharge

Abstract
Submerged multiport diffusers are often used to discharge waste heat resulting from once‐through cooling at coastal power plants. A particularly effective design, known as a staged diffuser, involves nozzles oriented offshore, parallel with the diffuser pipe. Potential flow analyses are used to describe the far field entrainment region for a staged diffuser discharging to quiescent receiving water of either constant depth or linear sloping bottom. Boundary conditions, in the form of a distributed sink, are supplied by a simplified near field model. Whereas near field theory shows that dilution can be increased by increasing discharge velocity, extending diffuser length or siting in deeper water, the latter options are shown to be preferable from the standpoint of minimizing induced velocities and the magnitude of nearshore entrainment.
