Mathematical model of the solar still performance using forced convection with condensation process outside the still

In this study a mathematical model is used to predict the performance of the solar still using forced convection inside the solar still to enhance the productivity of the still. Experimental study on the enhancement of solar still productivity using forced convection with condensation outside the still, shows that the productivity increases about 60% more than that of a natural convection solar still. The results of this theoretical study show that there is a relationship between the Reynolds number and the still productivity. Good agreement between the theoretical and experimental results is obtained. Enhancing mass transfer coefficients due to forced convection has a major role in the productivity enhancement.
