研究目的
To develop and test a new construction of a stepped solar still with slope surfaces and baffles to enhance the productivity of solar desalination systems, examining the effect of the new absorber plate design.
研究成果
The new design of the solar still with an inclined cascade absorber plate and baffles achieved higher temperatures (up to 68°C for the absorber plate and 40°C for the glass cover) and productivity (up to 1.6 kg/m2·hr) compared to conventional stills, demonstrating its effectiveness for solar desalination. Future work could focus on scaling up and long-term testing.
研究不足
The study is limited to specific days (February 15-16, 2017) and location (Rabat, Morocco), which may not represent year-round performance. The experimental setup uses a small scale, and further optimizations or comparisons with other designs are not extensively discussed.
1：Experimental Design and Method Selection:
The study involved designing and fabricating a cascade solar still with an inclined absorber plate featuring slope surfaces and baffles. The experimental setup included measuring temperatures and solar intensity to analyze performance.
2：Sample Selection and Data Sources:
Brackish water (15 liters) was used in the still, and data on solar intensity and ambient temperature were collected on February 15 and 16, 2017, in Rabat, Morocco.
3：List of Experimental Equipment and Materials:
Equipment included thermocouples (6 on the absorption surface, 3 on the glass cover), a saline water tank, and materials such as aluminum for the basin and absorber plate, glass cover, and synthetic rubber for sealing.
4：Experimental Procedures and Operational Workflow:
The still was fed with brackish water and operated for 13 hours per day. Temperatures and solar intensity were measured hourly, and productivity was calculated based on condensed water collection.
5：Data Analysis Methods:
Data were analyzed by plotting hourly variations of temperatures and productivity against solar intensity, using graphical methods to interpret results.
