MASS TRANSFER DURING AIR HUMIDIFICATION IN SPOUTED BEDS

摘要

This article presents the results obtained from analysing the impacts of bed media,static bed height,and the water-to-air mass flow ratios on the mass transfer coefficient and Colburn factor.The experimental data were compared with the correlations for mass transfer and the analogy between heat and mass transfer in conical spouted beds described earlier in literature.Moreover,the aim of the article is to present some new correlations of dimensionless groups for description of mass transfer and analogy of heat and mass transfer in sprayed spouted beds,which were developed by the authors.
