The global freshwater crisis necessitates innovative and sustainable solutions to meet the growing demand for clean water. One promising approach is atmospheric water harvesting through the condensation process, inspired by natural mechanisms. This technology utilizes hydrophilic surfaces and mechanical vibrations with waveform variations to enhance condensate release efficiency. This study aims to evaluate the influence of waveform variations at different vibration frequencies on condensation efficiency using hydrophilic copper plates. The methodology involves applying vibrations with various waveforms to the condenser plate. The vibration frequencies were adjusted to measure the rate and efficiency of condensate collection. Additionally, waveform variations were applied at each frequency to analyze their impact on accelerating condensate droplet release and refreshing surface areas for continued condensation. The results indicate that resonance mono frequency with square waveform can enhance the condensation rate by up to 300%. The effects of waveform variations significantly accelerated condensate release, opened new surface areas for condensation, and prevented the formation of thick condensate layers that could hinder heat transfer. This study confirms the potential of mechanical vibration-based technology in improving atmospheric condensation efficiency, contributing to the development of energy-efficient and sustainable water harvesting technologies.
