| Popis: | Nanofluids are the new generation of ultrafast heat transfer fluids due to their exceptional thermo-physical and optical properties and attracted attention of the researchers worldwide in recent times. Worldwide, research is underway to utilize the advances of nanotechnology for potable water production. In the present communication, the energy matrices, enviroeconomic analysis, and exergoeconomic analysis of passive double slope solar still (DSSS) has been carried out incorporating Al2O3, TiO2 and CuO-water based nanofluids. Significant enhancement in the annual productivity (Al2O3 19.10%; TiO2 10.38%; and CuO 5.25%), energy (Al2O3 26.76%; TiO2 19.36%; and CuO 12.96%), and exergy (Al2O3 37.77%; TiO2 25.55%; and CuO 11.99%) of passive DSSS system with nanofluids has been observed in comparison to the still with basefluid (water) only. On the basis of energy and exergy, the energy payback time (EPBT), energy production factor (EPF), life cycle conversion efficiency (LCCE), environmental cost and exergoeconomic parameter has been estimated for different interest rates (i = 4%, 8%, and 10%) and life span (maximum 50 years) of the passive DSSS loaded with proposed three different water based nanofluids. |
