| The limitations of water supply in different countries have led researchers to propose the use of solar still as one of the solutions to the problem of water limitations. In this research, single-slope solar still have been used. Among the innovations of this research, it can be mentioned the improvement of the construction and maintenance of the solar still box by using PVC materials with a sliding absorber plate, as well as the use of wave makers to improve the performance of solar still. the wavemaker by creating surface and deep turbulences and increasing heat transfer, in addition to improving the performance of the solar stills, also prevents the accumulation of materials that are caused by stagnant water and reduce the heat transfer coefficient from the absorber plate. The results of the use of the wave maker showed that with the increase in the number of wave makers, the daily production and efficiency of the improved solar still also increased and reached 4324 ml/m2 per day and 42.6% respectively, which is about 40.2% and 9.7% more than conventional one. The results of the economic study of the improved solar stills also showed that the cost of producing of each liter of fresh water in improved still equipped with wave makers was 0.013 $, which was about 13% less than conventional one. |
