  7. Abstract:
  8. Nowadays, the shortage of freshwater resources and their widespread pollution have become one of the most critical global challenges. Considering the limitations of natural water resources and the large share of saline water on Earth, seawater desalination has emerged as an effective solution. In this study, solar radiation is employed as a clean and sustainable source for evaporating saline water in an evacuated tube solar collector. To enhance the evaporation rate of the system, a vacuum is created based on Bernoulli’s principle through the passage of a water cycle in an ejector and the suction of vapor, thereby improving the system’s performance. To evaluate the performance, four operational scenarios were defined, and parameters such as water flow rate, suction intensity, and freshwater yield were analyzed. The results demonstrated that variations in these parameters have a direct impact on the evaporation rate and overall system efficiency. The highest freshwater production was recorded in the second scenario at a flow rate of 50 liters per minute, corresponding to 12.21 kg/m^2 . Furthermore, the economic assessment showed that the cost of producing each kilogram of freshwater was 0.0677 USD. The findings of this research indicate that utilizing solar energy in combination with ejector technology can provide an efficient and cost-effective approach for seawater desalination
