Experimental and theoretical investigation of a solar desalination to produce fresh water with active and passive states

This project is conducted to provide mathematical modeling as well as experimental investigation on a hybrid photovoltaic/thermal collector with solar still system. The performance comparison of the system with conventional solar desalination systems is the other result of the project. In this regard, two different experimental setup have been investigated: active mode (including solar still, heatpipe, and photovoltaic cells), passive mode (solar still, exclusively). At first, the convenient depth of brine water in the basin was determined. Then, the amount of distilled water on the solar still glass cover as well as its walls was measured. The maximum water recorded for passive mode is at 14:00 up to 0.292 Kg/m2 .h, and for active mode is 0.406 Kg/m2 .h at 14:00. The mathematical modeling was done based on thermodynamic and heat transfer relations convenient for the setup arrangement. The reliability of the model results is checked by the experimental results and a discussion is proposed
