Theoretical Analysis of Solar Distillation Using Active Solar Still

The performance of active single slope solar still using different operational parameters is studied theoretically and compared with the experimental data for validation purposes, to find out best factors enhancing still productivity.The thermal performance of a single slope solar still coupled with collector is evaluated through implementing the following effective parameters; a) different insulation thicknesses of 1, 2.5 and 5 cm, b) solar intensity, c) overall heat loss coefficient d) effective absorptivity and transmissivity, and e) temperature differences between the still cover and water and f) wind speed.It can be concluded from this study that active solar stills can be one of the options for enhancing the productivity of stills, while wind speed and insulation thickness can contribute to the enhancement of the overall yield.
