Effect of inclination of external flat plate reflector of basin type still in winter

Effect of inclination of the external reflector on the performance of a basin type solar still at various seasons

“…Furthermore, validation of some of the interesting, and perhaps unpredicted, conclusions from the theoretical study of Tanaka and Nakatake (2007b) at 30°N latitude in winter is another aim of this investigation.…”

“…However, the benefit of the reflector(s) and the effect of the inclination of the external reflector for the different months and seasons of the year have not been examined experimentally. Tanaka and Nakatake (2007b) conducted a theoretical analysis of a basin type solar still with an internal reflector and an inclined external reflector in a winter solstice day at 30°N latitude. Among their Energy for Sustainable Development 13 (2009) 244-249 conclusions regarding the effect of the external reflector were: (a) the productivity of the basin type still with both internal and external reflectors (IES) can be increased by inclining the external reflector in winter; (b) when the tilt angle of the glass cover is in the range of 20-40°, the external reflector angle should be set at about 15°to maximize the daily produced by an IES type still; and (c) for a still with a cover angle of 20°, the daily productivity of an IES type still with an external reflector at 15°would be 14% or 34% more than that of an IES type still with a vertical external reflector, and about 2 or 2.3 times that of a still without reflectors.…”

Experimental Validation of Optimized Solar Still Using Solar Energy

“…It was shown that the developed mathematical model is able to predict accurately the trends of the thermal characteristic of the optimized solar still system temperature of the optimized solar still. distiller coupled with a solar collector and the influence of inclination of water collector of conventional solar distiller unit were optimized [5]. An experimental parametric study of an active solar distiller integrated with a water solar heater and found that the maximum increase in the yield was up to 33% [6].…”

Experimental and analytical study on productivity augmentation of a novel solar humidification–dehumidification (HDH) system

“…External collector [12] and solar pond [13][14][15][16] were used to preheat water. External reflector plates [17] at different inclination angles were used to increase the radiation incidence on the solar still. Deniz [18] investigated the effect of parameters such as gap distance, slope of cover and cooling of the cover on the performance of the still.…”
