Absorption of Water Vapor into an Absorbing Binary Liquid Film Falling over a Horizontal Tube Bank

수평원관군상(水平圓管群上)의 이원흡수용액유동(二元吸收溶液流動)에 의(依)한 전달흡수특성(傳達吸收特性)

Condensation of water vapor into an absorbent liquid of LiBr-water solution falling over a bank of water cooled horizontal tubes was investigated theoretically. The governing conservation equation for a re-defined physical transport phenomena were solved numerically using a finite difference method. Raw parameters were used in this study, since reliable experimental data is required prior to a dimensionless parametric study. The average values of wall heat transfer coefficient and interfacial absorption rate were defined to see the system performance. Other parameters include tube diameter, streamwise coordinate (and number of tubes in row), mass flow rate, and the wall temperature. The effects of these quantities on the absorption processes and suggestions for a rational system design have been presented.
