Abstract

The fresh water reserves on the earth are finite. The brackish water can be converted to the fresh water by solar water distillery. A theoretical investigation to investigate the effect of the turning hollow-cylinder within the solar still equipped with flat plate solar water collector on the output of distillate water and its thermal efficiency. The numerical analysis was carried out by using FORTRAN 90, program. The numerical analysis is used for complex phenomena without resorting to expensive prototypes and difficult experimental measurements. The study considered several parameters which are; solar radiation intensity, ambient air temperature, ambient wind velocity, basin plate temperature, basin water temperature, glass cover temperature and hollow cylinder surfaces temperature. The cumulative of distillate water output from the modified solar still increased compared with the conventional solar still by a factor not less than 240%.
