Studies on performance of indices in cooling water system

چکیده
The usefulness and applicability of water indices such as Langelier saturation index, Ryznar stability index and Practical scale index for predicting the corrosive/scale forming tendency of chemically treated open recirculating cooling water has been studied. The study is based on the obtained corrosion and scale data for the period from May 1998 to December 2007, carried out at Fast Breeder Test Reactor, Kalpakkam, India. All the indices are calculated using pH, calcium, total dissolved solids, temperature and alkalinity of cooling water. Practical scale index and Ryznar stability index are found to be more informative than Langelier Saturation Index in keeping track of the corrosive/scaling tendency of the cooling water.

This paper experimentally studies the heat absorption performance of a heat sink with vertical embedded heat pipes in the aluminum blade. The cooling system with embedded heat pipes distributes heat from the CPU to both the base plate and the heat pipes, and then transfer heat from fins to the Environment. The thermal resistance and heat transfer coefficient are evaluated for natural convection...
