摘要

Purpose

Introduces a novel Ultrasonic Vibration-Assisted Solar Still (UVASS) using C46400 naval brass combined with CuO and TiO₂ nanoparticles to enhance evaporation, thermal conductivity, and system durability. Unlike prior studies, this approach attempts to ensure uniform nanoparticle dispersion and improved heat transfer through ultrasonic agitation.

Methods

The experimental setup includes the use of copper oxide (CuO) and titanium oxide (TiO2) nanoparticles, C46400 naval brass, and polyethylene foam as materials. After constructing the system, experiments are conducted under varying input conditions. Response Surface Methodology (RSM) is used to improve factors like vibration frequency (1000-4000 Hz), amplitude (5-15 mm), acceleration (up to 2500 m/s²), thickness of the absorber plate (1-2 mm), and the amount of CuO (6320 kg/m²) and TiO₂ (4230 kg/m²) nanoparticles.The experimental setup includes the use of copper oxide (CuO) and titanium oxide (TiO2) nanoparticles, C46400 naval brass, and polyethylene foam as materials.

Results

The proposed system achieved a maximum water yield of 26.25 L/day and thermal efficiency of 64.75%, representing a 60% improvement over conventional stills. The evaporation rate reached 6.65 L/m²/day, with a temperature increase of 6.7°C due to ultrasonic vibration, contributing to enhanced thermal performance. These results demonstrate the proposed system's superior performance and strong potential for sustainable freshwater production in energy-limited environments.

Conclusion

This study aims to address these challenges by integrating vibration-assisted technology with C46400 naval brass and optimizing parameters using RSM. The study effectively determined the key variables and interplay influencing the performance of solar stills, offering prediction models to improve solar distillation system efficiency.
