Experimental and theoretical analysis of single sloped basin type solar still consisting of multiple low thermal inertia floating porous absorbers

Thermal models of solar still—A comprehensive review

“…Srivastava and Agrawal [7] proposed a thermal model to analyze the performance of basin type solar still by incorporating multiple low thermal inertia porous absorbers (blackened jute cloth), floating adjacent to each other on the basin water with the help of thermocol insulation. Nine such absorber pieces were floated side by side lengthwise on the basin water so that the water surface was completely covered by the absorber with required clearance from the basin walls.…”

Effects of amount and mode of input energy on the performance of a multi-stage solar still: An experimental study

“…Passive systems [1][2][3][4] are those which receive no energy form non-solar energy sources while active systems [5][6][7][8][9] receive some energy from an external source in addition to the common solar energy to raise the temperature and consequently the evaporation rate of undistilled water. This external energy can be supplied by solar collectors [10][11][12][13] or the thermal energy wasted in industrial units [14].…”

Enhancing the solar still yield by increasing the surface area of water—A review

“…The schematic diagram of a solar still with low inertia floating absorber is in Figure . Srivatsa and Agarwal experimentally analyzed the solar still with modifications such as boosting mirrors and low inertia floating absorbers. The absorber was of blocks with thermocol pieces attached to jute cloth for floating effect.…”

“…As there is a greater need of fresh water, especially in the remote coastal areas, researchers have made several modifications in a solar still for improving the yield with increased free surface area. Method includes various wick materials on multibasin single‐ and double‐slope solar still , use of sensible heat storage such as rocks , pebbles , fins, sponges, shallow reservoir with wick material , porous fins , corrugated fins , mini solar pond with sponges , floating absorbers , sand reservoir , and solar still with baffles .…”
