摘要：
In the present study a triangular pyramid solar still is theoretically analysed by flowing air over the entire surface of the glass from the top to analyse the improvement in yield of fresh water. The effect of water mass and wind velocity was theoretically analysed. The results show that there is a significant improvement in the yield of fresh water to about 10.1 kg/m2 with a maximum velocity of air (U = 40 m/s) at a least water mass of 20 kg inside the basin. For practical cases the yield of fresh water depends on naturally occurring wind velocity and the results show that the improvement in yield is 104% with an increase in velocity from 0.5 to 4 m/s. © 2016 Informa UK Limited, trading as Taylor & Francis Group.
