Energy and exergy analysis of single slope single basin solar still

A single slope basin type solar still has been designed and fabricated. The still is provided with a dripping arrangement to pour saline water drop by drop in the basin. Thermal modelling has been proposed based on the energy balance equations of the temperature elements of the still. A computer program has been written for the analytical solutions for the temperature of glass cover, water and basin, respectively, and numerical results are validated with the experimental for one of the typical days in summer and winter (2 October 2010 and 30 May 2011). The numerical results are in close agreement with the experimental results. Also exergy and energy analysis have been carried out to find the parametric influence on the performance of the still and to evaluate the fractional exergy and energy, instantaneous exergy and energy efficiency of the still.
