Abstract

The growing global population on the one hand, as well as the scarcity of fresh water resources, are the reasons for the global water crisis. Therefore, to cope with these conditions, humans need to find alternative and renewable freshwater sources through the treatment of existing unhealthy waters or desalination of saltwater. Staircase solar water purifiers are among the many devices used in water purification. This paper deals with the simulation of a staircase solar water desalination at the University of Sistan and Baluchestan with Comsol software. After comparing the experimental data and the results of the software, the influence of saline depth parameter on the stairs on the amount of fresh water output from desalination was investigated. For this purpose, the performance of the device for saline water depths of 0.005, 0.0075 and 0.01 m with inlet saline flow rate of 0.2 (kg / min) was investigated. The results show that with increasing salt-water depth, the water temperature decreases and the temperature difference between the water surface and the glass surface decreases and the amount of fresh water produced decreases.
