A new method of control on heat pollution in cooling pool in power plant

A new method of control on thermal pollution of cooling pool in power plant is discussed in this thesis under the principle of combining production, research and design. The model test takes colored water as tracer and gives experimental results of how the three dimensional successive points, which are distributed in the entrance and exit of water in a manner of march past, change into infinitely long two dimentional faces by constructional facilities. Two approximate calculating formulas are also introduced. One is the flow speed distribution in water exit area and the other is the changing rate of water flow. This new method has great practical value on exploiting the potential heat radiating in cooling pool and enlarging the installed capacity of power plant.
