Use of nanoparticle-embedded phase change material in solar still for productivity enhancement

In solar still, during the peak hours of day, inside air becomes saturated with water vapor which makes the evaporation process slow and increased convection and radiation heat losses due to high temperature.

Description
Summary:In solar still, during the peak hours of day, inside air becomes saturated with water vapor which makes the evaporation process slow and increased convection and radiation heat losses due to high temperature. Phase change materials (PCM) is used to store the surplus solar energy, which obstruct the temperature rise and increases the productivity. Further, charging and discharging period of PCM can be reduced by embedding nanoparticles. Experiment study has been carried out to evaluate the augmented distillate productivity using nanoparticles enhanced PCM (NEPCM) in solar still. Experimental study of solar still having V-corrugated plate with paraffin wax embedded with CuO nanoparticle was done and found that productivity of different Nanoparticles of 0.1%, 0.2% and 0.3% was 440, 455, 510 ml/0.25 m2 day−1.
