A Study on Heat and Mass Transfer Analysis of Solar Still

Abstract

To evaluate the performance of solar still, it is very important to know about the energy balance and heat transfer. Heat transfer phenomena occur inside the still through three variable modes convection, evaporation, and radiation. As the temperature of water increases, the evaporation rate also increases. Therefore, many modifications have been done to increase the evaporation rate of basin water by the researchers, such as using nanoparticles, photovoltaic module, flat plate collector, heat exchangers, and phase change materials etc. The heat and mass transfer study on different parts of SS along with energy balance is presented in the paper. The reader will get information about the quantity of heat absorbed and the heat released inside the basin. Modification made on SS to increase productivity in the last 4-5 years has also been presented. The study found that the productivity of modified solar still gives 53.95% higher than the conventional solar still after adding external devices and energy storage
