Different parameters affecting the rate of evaporation and condensation on passive solar still - A review

Scarcity for water exists in many countries even though three-fourth of the earth is covered by water. The reasons for scarcity of water are worldwide rapid growth of industry and immeasurable population. Solar still is the only efficient solution for water problem in hot climatic conditional areas where scarcity of water and electricity occurs. Solar still is a very simple solar device that is used for converting the available brackish water into potable water. Investigation shows that the productivity of basin type solar still is limited. Various literature reported several experimental and numerical investigations on basin type of solar still. An extensive review on different parameters affecting the rate of evaporation and condensation on passive solar still has been carried out in this paper. (C) 2014 Elsevier Ltd. All rights reserved.
