Modeling and Analysis of Contactless Solar Evaporation for Scalable Application

Zero-liquid discharge wastewater treatment driven by sunlight shows potential to minimize its environmental impact producing solid-only waste from solar energy. To overcome the key barrier of absorber contamination, solar-driven contactless evaporation (SCE) has been proposed. However, only a small-scale laboratory device studied, which cannot support scalable application. analyze SCE, it is essential understand conjugated heat and mass transfer under application scenario. In this study, comprehensive model SCE developed, validated test applied Results showed that (0.313 kg·m−2·h−1) could obtain higher rate than (0.139 due suppressed losses sidewalls. If design parameters are finely tuned thermal insulation properly applied, be further enhanced 0.797 kg·m−2·h−1, indicating 473.3% performance enhancement SCE. The modelling framework understanding expected pave way for improvement
