Comparative Analysis of Double Slope Solar Still Using Al2O3 Nanofluid with Conventional Double Slope Solar still

Mechanical Engineering

Clean water is a basic need for human and life is impossible without water. As the available fresh water is remains same on earth surface and its demand is increasing day by day due to increasing population on surface of earth and also the rapidly increasing of industries, hence there is an essential and earnest need to get potable water from the saline/brackish water present on or inside the earth. One of the method uses for getting fresh water from saline water is solar distillation this method is simple and economical then other methods. But the distilled of the single basin solar still have very low yield of water. Utilizing nanofluid as an absorber fluid mixing with water is an effective approach to enhance heat transfer in solar still device. In this Research, Attempts are made to make a double slope solar still. The overall size of the basin used Is 300mmx600mmx100mm. The experiments have been conducted to determine the performance of a solar still in climate conditions of Valsad (20.63ºN,72.93ºE, elevation 17 m), Gujarat. This experiment compares the single basin double slope solar still with Aluminum Oxide (Al2O3) nanofluid and without nanofluid. Two experimental stills of the same basin size are fabricated and tested the performance of single basin double slope solar still with and without nanofluid simultaneously.
