Design of a Stratified Cooling Channel

by R. E. Baddour, Univ of Western Ontario, London, Canada,

Abstract: Cooling ponds are used for managing waste heat discharges. Cooling ponds are, however, expensive to construct and operate. A cooling channel is studied as an alternative means of managing thermal discharges. An exchange flow in the cooling channel leads to higher dilution rates. A thermal-hydraulic model of the cooling channel, with a nonlinear equation of state, is presented. Computer simulations are used to demonstrate the design of a cooling channel when a temperature constraint is imposed at its outlet.
