Multiple-effect

A number of seawater desalination technologies have been developed during the last several decades to augment the supply of water in arid regions of the world. Due to the constraints of high desalination costs, many countries are unable to afford these technologies as a fresh water resource. However

Indoor experiments were performed for the vertical multiple-effect diffusion-type solar still that consists of a number of vertical partitions in contact with saline-soaked wicks with narrow air gaps between partitions, coupled with a heat-pipe solar collector, using heating lamps instead of actual

We proposed a newly designed, maritime lifesaving small distiller consisting of a windmill and a number of horizontal concentric cylindrical partitions in contact with saline-soaked wicks. The wind energy is directly converted to frictional thermal energy in a liquid heat medium forming a thin layer

This paper presents a new maritime lifesaving multiple-effect solar still design where several extended wicks feed seawater to their evaporating areas by capillary force, and the resulting water vapor diffuses and condenses on facing wicks with the condensate flowing through the wicks into storage b

Solar thermal systems that produce potable water from salty water have been studied for quite some years, and the use of solar energy to produce potable water was known in ancient Egypt. Various solar thermal systems have been presented in the literature. The most studied model, the still type solar

Different flow sheets for thermal desalination processes were simulated using the computer program Evapolund. This general software is modular in structure and includes a number of modules describing different components in an evaporation process such as evaporators, different types of heat exchange
