Impetus Yield of Acrylic Top Cover Pyramid Solar still due to Furthered Thermal Conductivity of MnO₂ and PANI-MnO₂ Nanocomposite Materials

Abstract

Attempts to study the effect of blend MnO2 and PANI-MnO2 nanocomposites in enhancing the productivity of an acrylic Pyramid Solar Still (PSS) is carried out. Synthesized nanocomposites assorted with black paint to improve the absorption efficiency. Size of the synthesized MnO2 is found to be 35nm. SEM image infers particles are aggregates with random shape. Thermal analysis if distillate yield confirms the formation of nanocomposite with improved thermal stability of the PANI. Distillate yield is observed around 0.484 litre/0.25m2, 0.568 litre/0.25m2 and 0.615 litre/0.25m2 still without and with MnO2 and PANI-MnO2 nanocomposites. Average efficiency is found to be 23.05%, 26.63% and 28.52% under three modes. Efficiency of the combined performance is amended due to the absorption properties of MnO2 and PANI-MnO2. Performance ratio under three modes are found to be 5.52 %, 6.44 % and 6.93 %. Results concluded that saturation vapour pressure and latent heat also plays a major hole in production of distillate yield.
