| -- | This thesis is divided into two parts. Part one: a comparative energy and exergy efficiency study of hemispherical solar still and a single-slope solar still. The overall daily productivity was improved by 47.96% for the hemispherical solar still compared to the single-slope solar still. The maximum daily energy efficiency and exergy efficiency of the single-slope solar still are 25.81 and 1.8%, respectively, and for hemispherical solar still are 38.61 and 3.1%, respectively. The main conclusion from the study is the hemispherical distillery greatly enhances productivity as compared to the single slope distillate and gives more efficiency. Thus, the hemispherical solar still is recommended to be used to provide safe drinking water from salty water.<br/>Part two: The hemispherical distiller characteristics are having a large surface area for receiving and condensing compared to a conventional single-slope distiller. To achieve the maximum possible utilization of this feature, in first the Al2O3 nanoparticles were adding to the basin water to increase the evaporation rate, in the second modification the glass cover cooling technology was utilized to increase the condensation rate. To investigate the influences of Al2O3-water nanofluid and the glass cover cooling technology by a water sprinkler on hemispherical solar distiller performance, three hemispherical solar distillers were designed and tested in the same climate conditions. The first is the reference case (conventional hemispherical solar distiller), second is the modified hemispherical solar distiller with Al2O3-water nanofluid, and the third is the modified hemispherical solar distiller with Al2O3-water nanofluid and water sprinkler. Three different concentrations of Al2O3 nanoparticles 0.1, 0.2, and 0.3% were studied. Results showed that, the improvement 41.8, 50.9, and 61.3% of the volume friction of 0.1, 0.2, and 0.3%, respectively. Also, the improvement for utilizing the Al2O3 nanoparticles and water sprinkler reached 105.8, 110.4, and 121% for nanoparticle concentrations 0.1, 0.2, and 0.3%, respectively as compared to the reference case. |
