Abstract

Reversibly used cooling towers (RUCT) are used to extract heat from atmospheric to water. In this study, the factors influencing the value of Lewis number in a RUCT are analyzed by experimental investigation. The results show that Lewis number increases with the increase of water−air flow rate ratio. When the water−air flow rate ratio is constant, the Lewis number decreases with the increase of inlet water temperature and inlet air wet-bulb temperature, increases with the increase of inlet air dry-bulb temperature and water sprinkle density. This research offers a fundamental basis for studying heat and mass transfer characteristics in a cross flow reversibly used cooling tower and practical application.
