Theoretical Analysis and Experiment of Bubbling Humidification Flux

Abstract:

In this paper, basing on fundamental equations of double films and mass transfer theory, the theoretical expression of air humidification flux is deduced; according to the expression, the major factors influence the humidification flux on single hole bubbling are water temperature, air temperature, air flow rate, partial pressure of initial vapour in air, diameter of bubble, etc. High-speed camera technology is used to photograph the experiment of single hole bubbling humidifyication; according to the results of experimental measurement and photographing, the humidification flux is calculated under different diameters of sieve holes, water levels and air flow rates, and found it's related to the bubble diameter, it provides an effect method to calculate humidification flux by visual experimental data.
