In this communication, an effect of inclination of condensing cover and water depth in still, on convective mass transfer coefficient in passive solar still has been studied. Three solar stills with effective basin area of 1 m2 for three inclinations of condensing cover namely 15°, 30° and 45° have been considered. Another still with same effective area but fixed cover inclination of 30° is considered to see the effect of water depths on still performance for water depths 0.04m, 0.08m, 0.12m, 0.16m and 0.18m. Outdoor experiments have been conducted for Delhi climatic condition. Hourly variations of water, vapor, and cover temperatures along with yield have been measured. Regression analysis is used to determine the convective heat and mass transfer coefficient for outdoor condition. The 45° condensing cover is found giving maximum yield and lower water depth responded for higher yield in winter climatic condition.

A single basin single slope solar still with 0.82mx 0.81m x 0.75m has been fabricated with G.I sheet and tested with different water depths of 2,3,4cm. Various solid and liquid sensible heat storage materials, Evaporative surface materials are used in the form of billets, in the still. To reduce glass cover temperature the outer glass was cooled by using sprinkler manually at regular interval of time. Theoretical analysis was performed and compared with experimental values. The performances of modified still were compared with conventional still of same size running under the same meteorological conditions. The solid sensible heat storage materials produces48% more productivity than conventional still. Liquid sensible heat storage material produces 19% more than conventional in till. The payback period of the still was 340 days.

This study presents a theoretical model to simulate the temperatures and productivity of a single-slope, single-basin solar still when an external solar enhancement is used. Experiments were performed in the New Mexico region (32.3199° N, 106.7637° W) to validate the numerical model. A point focusing Fresnel lens was used in the experiments to enhance the solar input. It was found that a significant rise in the productivity of the still was achieved with the Fresnel lens. Parametric study by varying the water depth showed the Fresnel lens was more effective for larger water depths. In addition, the Fresnel lens can aid in improving the overall efficiency of the solar still.
