EXPERIMENTAL INVESTIGATION OF A SINGLE SLOPE SOLAR STILL USING PCM

A single slope single basin solar still is experimented by adding a heat reservoir under the liner of the basin using Lauric acid as a Phase Change Material by which it changes its phase during addition or removal of heat. Numerical and analytical calculations are performed and it is observed that an increment of 36% is observed in the collection of distillate when the still is used with PCM as Lauric acid and also 13% increment when the still is used with sand as heat reservoir. © 2011 Universal Research Publications.
