Abstract
We present a modification of a mass transfer theory developed by Spalding to predict mass transfer rates in solar stills of different inclinations. In previous applications to solar stills, the authors considered the mass fractions at the evaporating surface and the bulk state to evaluate the driving force for mass transfer. In this study, the mass fraction at the condensing surface on the cover is employed instead of the bulk mass fraction on the moist air in the still, since the former can be more accurately determined. Predicted results from the modified theory and results from relation of Dunkle 1 are compared with experimental values. The results of the modified theory agree very well with the experimental results, whereas Dunkle's relation is accurate only in horizontal stills and stills with small inclinations.
