Viability assessment of enhancing dry cooling systems using thermal storage ponds
Dry cooled systems are employed to reject heat in modern power plants. Unfortunately, these cooling systems become less effective under windy conditions and when ambient temperatures are high. One proposed solution to this problem is to augment the cooling capacity of the dry cooled system by means …

Simulation models for assessing the effects of power plant cooling systems upon protozoans
… flowed in the same manner into a cold water bath cooling it back to its original temperature. The water was then directed into three plexiglass troughs 79 cm. long, 5 cm. wide, and 7.5 cm. high, before it fell over an end plate 4 cm. high back into the artificial stream. Two control troughs were …
