Effect of Water Level and Glass Tilt Angle on the Performance of Solar Still

Vikas Kumar Thakur, Ravi Kushwah, Prateek Arora, M.K. Gaur

Abstract


This study presents testing and optimization of solar still at three different glasses tilts angles (11°, 26° and 41°) and water depths (4, 5 and 10 cm) for Gwalior climatic condition. Experiment is performed in the winter season and find out the optimum angle and water depth for winter climatic condition. Optimal tilt angle and water depth were found to be 41° and 4 cm respectively for the winter season. It was revealed that as the water level is decreased, productivity was increased. 4 cm water depth and 41° glass tilt angle gives maximum 1430 ml/day distilled water compare to other water depth and tilt angle. 41° glass tilt angle and 4 cm water depth also obtained maximum evaporative, radiative and convective, heat transfer coefficient (HTC).
