Experimental Investigation on Solar Desalination Using Copper Oxide Nano fluid

The main objective of the study is to review the various factors that play a role in increasing the desalinated water prices up and to find an alternative solution for it. Here the heat exchanger uses nano fluid as exchanging material and solar thermal power is used. Hence we are about to see whether these changes are efficient in bringing down the cost. The present study introduces an attempt for the application of flash desalination technique for small scale needs. An integrated system uses a flashing desalination technique coupled with nano-fluid-based solar collector as a heat source has been made to investigate both the effect of different operating modes and that of the variation of functioning parameters and weather conditions on the fresh water production. The thermal properties of working fluid in the solar collector have been improved by using different concentrated nano-particles. The volume fractions of nano-particle in solar collector working fluid have a significant impact on increasing the fresh water production and decreasing cost. • The solar thermal power is used as a heating source to bring the water to a temperature in which it produces steam. • This might be an alternative energy source for the existing conventional type of desalination. • The difference with this research is that the heat exchanger fluid used here contains Cuo nano particles which makes it to be a CuO nano fluid, thus enhancing the heat transfer.
