Integrated solar still with an underground heat exchanger for clean water production
A simplified model of heat and mass transfer of integrated solar still with an underground heat exchanger (GHEX) is presented.The solar still has 70 m length and 0.5 m2 inlet area.Moreover, the underground heat exchanger was 70 m length and 0.2 m diameter.The model includes a theoretical analysis in the transient mode for both the solar still and u
