Theoretical and experimental study of a pad humidifier used in a seawater desalination process Original Research Article

This paper presents an experimental and theoretical study of a pad humidifier used in a new multi-stage solar desalination process in operation in Tunisia. The experimental operation of the humidifier is presented in terms of temperature, relative and absolute humidity, and the quantity of evaporated water for different climatic and working conditions. A global simulation of the pad humidifier is presented. The Newton-Raphson method was used to solve the conservation equations. A comparison between theoretical and experimental results is also presented.
