چکیده
|
The current study investigates the optimization of productivity of solar stills (sss) at different levels of solar radiation intensity, film cooling flow rates, and water depths. in this regard, taguchi method was applied to perform few experiments and find the optimal water depth and cooling rate that could maximize the productivity. an l₉ orthogonal array, signal-to-noise ratio, and analysis of variance (anova) were used to investigate the influence of the operating parameters on the ss productivity. the results from taguchi method and anova revealed that water depth was the most influencing parameter. according to the results, while increasing the solar radiation and water film cooling would improve the productivity, increasing the flow rate more than 4 kg/hr had a negligible effect on the productivity. however, decreasing water depth would significantly enhance productivity due to faster rates of evaporation and condensation. this improvement in productivity by film cooling was about 6.05% at the optimal water depth of 0.5 cm while the cold-water flowed over the glass at 2 kg/hr. a regression equation was formulated to determine the relation between the operating parameters as independent variables and the productivity as a dependent variable.
