Experimental Validation of an Enhanced Solar Still with a Rough Rotating Drum

Solar stills are considered a promising option for obtaining fresh water when needed, especially in rural areas. However, the low water yield is the main drawback of these systems. Therefore, several studies have been dine to increase the system's water yield. In this work, a rough rotating drum was integrated with the system to enhance the obtained water yield. A predictive mathematical model was developed to account for the obtained water yield under the effect of roughness. The model was validated experimentally, where results showed a good agreement between modelled and experimental results.
