Asymmetrical Solar still Coupled with the Mini Solar Pond: Performance Evaluation on Clear, Partially Cloudy and Cloudy Days

Article Preview

Abstract:

A single-slope solar still with the basin area of 1m x1m and slope of 13 was fabricated and tested in Anna University, Chennai. Both the inner and outer walls were coated with black paint in order to improve the heat transfer rate. The bottom and side losses of the still are considerably reduced, due to the porous material beneath the basin liner. Effect of solar pond coupled with the still are experimentally investigated on a clear, partially cloudy and cloudy days and found that clear day has the maximum productivity. A model economic analysis calculation for single basin solar still coupled with pond is also done and the results are reported in this paper.
