  • Publication number: 20110011556
    Abstract: A water discharge system enhances heat transfer to the atmosphere by limiting the mixing of heated discharge water with the ambient water of a receiving water body. The heated water is maintained near the top surface of the receiving water body which increases the transfer of heat to the atmosphere as compared to a system where the discharge water is mixed quickly with the ambient water.
