CHARACTERISATION OF SOLAR STILLS

Abstract

This paper presents the transient analysis of a conventional solar still and the derivation of suitable parameters to assist in the characterization of various designs of solar stills. The methodology to test and compare the various designs of solar stills is presented. Further an attempt is made to incorporate the effect of glass cover inclination and the resulting triangular cavity volume on the performance of solar still. The expressions given by various authors are considered to take into account the glass cover inclination. Based on experimental and theoretical computations it is inferred that there is good agreement between experimental and theoretical results.
