Passive Screen Water Intake Design Studies
Publication: Journal of Energy Engineering
Volume 112, Issue 2
Abstract
Experimental and analytical studies are conducted to develop a novel water intake design for the prevention of fish impingement and excessive damage to fish larvae. Requirements by the regulatory agency lead to the use of cylindrical screens mounted in pairs on “risers” connected to four manifolds, which in turn were connected to an 18 ft diam withdrawal pipe carrying a total flow of (818 cfs) to a powerplant condenser. Separate model studies conducted on individual screen panels, individual and multiple risers and manifolds are described. The studies conducted at scale ratios ranging from 1:20‐1:3 are described. The system buit in 1981 continues to work well with only minor damage sustained by ice.
