Effect of Al2O3 nanoparticles on the performance of passive double slope solar still

Abstract This paper present the enhancement in yield (productivity) of passive double slope solar still (DSSS) using Al2O3 nanoparticles in the basefluid (water) for two different masses 35 kg and 80 kg. The analytical expression of fluid temperature has been derived for passive DSSS. On the basis of developed model, the analysis has been carried out for the basefluid (without nanoparticles) and for nanofluid with three different concentrations (0.04%, 0.08% and 0.12%). Effect of different concentrations of Al2O3 nanoparticle on fluid temperature, thermal conductivity, internal heat transfer coefficients (HTC) and yield of the fluid has also been analyzed. For 0.12% concentration of Al2O3 nanoparticles, the enhancement of yield for 35 kg and 80 kg basefluid has been found to be 12.2% and 8.4% respectively as compared to that of basefluid.
