Solar distillation

The aim of this study is to investigate analytically and experimentally the effect of using an induced atmospheric air, water heaters, external reflector and weather condition on the performance augmentation of humidification– dehumidification (HDH) system. This novel HDH system is a modified solar stil

The characteristic equation has been used for experimental results of a passive solar still to generate linear and non-linear characteristic equations for winter and summer conditions. The different angles of inclination of condensing cover (15°, 30°, 45°) have been chosen for winter and summer cond

In this paper, we present a geometrical model to calculate the radiation reflected from an external reflector inclined backwards and then absorbed onto a basin liner of a basin type still. The effect of the inclination of the external reflector on the distillate productivity of the still with both t

This paper presents a theoretical analysis of a one step azimuth tracking tilted-wick solar still with a vertical flat plate reflector. The still is assumed to be rotated manually just once a day at southing of the sun. We performed numerical analysis of heat and mass transfer in the still to determ

This paper deals with the MEDESOL (Seawater Desalination by Innovative Solar-Powered Membrane Distillation System) project, partially supported by the European Commission under the Horizontal Programme “Global Change and Ecosystems (Global 4)”. Despite the advantages of solar membrane distillation (

An attempt has been made to evaluate inner and outer glass temperature and its effects on yield. Numerical computations have been performed for a typical day in the month of December, 2005, for the climatic condition of New Delhi (latitude: 28E35N N; longitude: 77E12N E and an altitude of 216 m abov

A detailed analysis of low power (100 kW) solar-driven Rankine cycles in the medium temperature range has been carried out. Toluene, octamethylcyclotetrasiloxane (D4) and hexamethyldisiloxane (MM) has been considered as working fluids of organic Rankine cycle (ORC). Direct solar vapor generation con

This paper presents a numerical analysis to investigate the effect of the vertical flat plate external reflector on the distillate productivity of the tilted wick solar still. We propose a geometrical method to calculate the solar radiation reflected by the external reflector and absorbed on the eva

Different theoretical and experimental studies carried out in the field of solar distillation with green-house effect, have shown that global efficiency of a simple solar still are affected by physical and building parameters, especially by the difference of temperature between the evaporation surfa

The objective of this research project was to develop a process that makes use of low-grade heat provided from solar irradiation to drive a distillation-desalination process. An optimized distillation process re-uses input heat, by using the heat-of-condensation as the heat source for pre-heating th
