Preliminary Concepts
Published in Hillel Rubin, Joseph Atkinson, Environmental Fluid Mechanics, 2001
As noted previously, there are many forms for f(W) suggested in the literature. Other than modeling natural water bodies, a specific engineering application for these calculations is in the design of cooling ponds for disposal of waste heat from power plants. There the effects of free convection are much more important than for a natural water body, and research has focused more on developing expressions for buoyancy effects. For any application, the choice of f(W) depends on the relative importance of forced and free convection effects. Ryan and Harleman (1973) suggested a formula that incorporates both effects,

Heated water generated by power plants or manufacturing plants may be controlled with: cooling ponds, man-made bodies of water designed for cooling by evaporation, convection, and radiation.Cooling towers, which transfer waste heat to the atmosphere through evaporation and/or heat transfer.Cogeneration, a process where waste heat is recycled for domestic and/or industrial heating purposes.
Applications of Computational Heat Transfer

Cooling ponds are natural or arti cial water bodies that are employed for the disposal of rejected energy from power plants and industrial units. The water body exchanges energy with the ambient environment at the surface and with the ground at its sides and the bottom. The heat lost to the ground is generally negligible compared to the exchange at the surface for large water bodies. The natural temperature cycle of a water body is, therefore, largely a consequence of the time-dependent energy exchange at the surface. The energy lost at the surface q, per unit area and time, may be given as:

Power plants consume large volumes of water, most notably in the production of steam for powering the turbines. The actual quantity of water consumed by thermal electric power plants (natural gas, coal, and nuclear) depends on which of the three cooling technologies are employed: once-through cooling (cooling pond), recirculating cooling (wetcooling tower) or dry-cooling (air-cooled condenser).
