Abstract: This paper presents the improvement achieved in the efficiency and productivity of distilled water from a single slope side solar still by using the nanofluids technology. Effects of various parameters, namely, solar intensity, ambient temperature, water salinity, glass cover have been examined. A single slope side solar still with basin floor surface area of was designed, developed and tested using different concentrations by weight (0.05, 0.1, 0.15, and 0.2%) of the CuO nanoparticles in the saline water under climatic conditions of Kuwait. In this study, the main objective is to improve the efficiency and productivity of solar still systems. A series of experiments were carried out testing the solar still and the experimental data collected was compared with base case (without using the nanoparticles in the saline water). The results showed that the use of nanofluids particles mixed with water in the basin increases the rate of evaporation and hence the still efficiency and consequently the solar still output productivity of distilled water. Finally, it is noted that for the experiment using nanofluids concentration by weight of 0.1%, CuO in the basin saline water increased the productivity by 100% and solar still efficiency by 111.2%. The estimated cost for the proposed still is 168KD (1KD $3 approximately). |
