Exploring Trapezoidal Salt Gradient Solar Pond Performance A Combined Numerical and Experimental Analysis with and without Reflective Covered Surface

This study investigates the thermal performance of trapezoidal salt gradient solar ponds through a combined approach of experimental analyses and MATLAB numerical simulations. Salt gradient solar ponds offer a promising solution for sustainable energy generation by harnessing solar radiation and storing it as thermal energy for various applications. However, optimizing their performance is essential to maximize energy efficiency and economic viability. Laboratory experiments were conducted to evaluate the thermal dynamics of trapezoidal salt gradient solar ponds under different conditions, including the presence or absence of a reflective covered surface. These experiments provided valuable empirical data on temperature distribution and heat storage capacity. Additionally, numerical simulations were performed using MATLAB to model the thermal behavior of the ponds and validate the experimental findings. The simulations allowed for a deeper understanding of the underlying mechanisms governing heat transfer and energy storage within the ponds. The results revealed significant insights into the impact of the reflective covered surface on the thermal performance of trapezoidal salt gradient solar ponds. Specifically, it was found that the introduction of a reflective cover led to an 8-degree increase in temperature compared to ponds without a cover. This temperature enhancement is crucial for enhancing the overall efficiency of the solar pond system and increasing its potential for energy generation. Furthermore, outdoor contrast experiments, involving two mini solar ponds with a surface area of 0.42m×0.42m and a bottom area of 0.09m×0.09m, provided valuable insights into the real-world performance of the ponds under natural conditions. The combined experimental and numerical approach facilitated the identification of optimal design parameters and operational conditions for trapezoidal salt gradient solar ponds. By leveraging both empirical data and computational modeling, this study contributes to the ongoing efforts aimed at advancing the development and implementation of solar pond technology for sustainable energy production. In conclusion, this research underscores the effectiveness of trapezoidal salt gradient solar ponds as a renewable energy solution and highlights the importance of reflective covers in enhancing their thermal performance. The findings offer valuable insights for engineers, researchers, and policymakers striving towards a more sustainable energy future.
