Abstract [en]

This study investigates the possibility of using warm humid air for irrigation and drinking water production, by flowing air over the water surface in a solar still with saline or polluted water. Vapor will be saturated during mixing with the warm air in buried pipe. Finite difference method is employed to simulate the flow of the air long the pipe. The amount of water produced and buried pipe length depends upon the flow velocity, humid air properties and buried pipe diameter. The amount of water produced is 0.02525kg/s (0.0909m3/h). The length of the buried pipe needed in this study is 77.36m for a selected air flow velocity 5m/s with the properties of 70°C, 100% relative humidity at pipe inlet, 40°C and 100% relative humidity at pipe outlet of 0.2m pipe diameter. The results agree with a previous study (Gustafsson & Lindblom, 2001) with -4.0% deviation in water production and 7% of required pipe length
