Abstract
This study presents a strengthened numerical modeling and parametric analysis of a solar-driven humidification–dehumidification (HDH) desalination system operating in a closed-air/open-water configuration. A one-dimensional model coupling heat and mass transfer equations is developed to describe the thermo-hygrometric behavior of the air stream and the air–water interaction within the system components. The model predicts the evolution of air temperature, humidity ratio, and freshwater production as functions of inlet operating conditions. A multivariable parametric study is conducted to assess the influence of air inlet temperature, water depth, and feed water salinity on system performance. The results demonstrate a strong enhancement of productivity with increasing air inlet temperature, while higher water depth and salinity adversely affect mass transfer and water yield. An optimal operating range is identified to improve system efficiency. The outcomes provide a reliable theoretical framework for system optimization and future experimental validation of the solar HDH prototype.
