Coupled Heat and Mass Transfer during the Absorption of Water Vapor into LiBr-H₂O Liquid Solution Flowing down the Outside of the Horizontal Cylinder

수평원관상의 LiBr-수용액에 수증기가 흡수될때의 열 및 물질전달

The problem of heat and mass transfer accompanying the absorption of water vapor into LiBr-$H_2O$ liquid solution flowing over the outside of the horizontal cylinder was theoretically studied to understand the absorption process occuring in the absorber of the absorption heat pump. Numerical results are presented for various quantities of interest relating to temperature, concentration, heat flux and mass flux. Also, the effects of mass flowrate, initial average velocity, and the radius of the cylinder were investigated.
