Mathematical modeling of an inclined solar water distillation system

Abstract

An inclined solar water distillation (ISWD) system, which generates distilled water (i.e., condensate) and hot water at the same time, was modeled and simulated. In the parametric studies, the effects of feed water mass flow rate and solar intensity on the system parameters were investigated. Finally, the system was simulated using actual deviations of solar intensity and environment temperature during a typical summer day in North Cyprus. The system can generate 3.5-5.4 kg (per m(2) absorber plate area) distilled water during a day (i.e., 7 am till 7 pm). The temperature of the produced hot waterreached as high as 60 degrees C, and the average water temperature was about 40 degrees C, which is good enough for domestic use, depending on the type of feed water. The simulation results are in good agreement with the experimental results.
