Construction and Performance Analysis of a Single Slope and a Pyramid Cover Solar Still with Storage Media and Electrical Backup

Abstract

The Main objectives To construct a Single Slope and Pyramid Solar Stills To study the individual thermal performance of the Single Slope and Pyramid Solar Still To analyse the thermal performance of the two stills Single Slope and Pyramid Solar Still with thermal storage medium such as Tar Coated Blue Metal absorber To analyse the thermal performance of the two stills Single Slope and Pyramid Solar Still with with Phase change material Wax To analyse the thermal performance of the Pyramid Solar Still coupled with electrical back up To study the instantaneous and overall efficiencies of these two stills Single Slope and Pyramid Solar Still To develop a simulation model for the solar still To analyse the internal and external heat transfer modes for individual and combined with absorbing materials To analyse the thermo physical properties of water in all performance studies To analyse the behaviour of Nusselt Grashof Prandtl and Rayleigh Numbers in all performance studies To analyse improvement in distilled yield in the two stills Single Slope and Pyramid Solar Still performance
