Abstract
Desalination of seawater plays an important role in short water supply which is one of the global environmental problems. Solar desalination system is more desirable for global environment than that using fossil fuels. A conventional roof type solar still using newly transparent film instead of usual glass cover was studied by computer simulations using a numerical one-dimensional model in outdoor and indoor experiments. The experimental results showed that an increase in the wind speed on the roof brought an increase in difference of temperature between water and the film cover, resulting, an increase in the still yield.
