The measured data of global solar radiation on a horizontal surface, as well as the number of sunshine hours, mean daily ambient temperature, maximum and minimum ambient temperatures, relative humidity and amount of cloud cover, for Jeddah (latitude 21° 42'37''N, longitude 39° 11'12''E),...

Transient mathematical models are presented for a single slope-single basin solar still with and without phase change material (PCM) under the basin liner of the still. Analytical expressions for temperatures of the still elements and the PCM have been obtained. The still performance has been...

An indirect type natural convection locally made solar dryer, consisting of a flat-plate solar air heater connected to a drying chamber, has been investigated experimentally and theoretically. The system is used for drying fruits and vegetables such as seedless grapes, figs, green peas, tomatoes...
