Abstract
젖은 벽탑을 사용하여 증류수에 의한 공기중의 산소의 물질전달에 대하여 온도와 액체유량의 영향을 연구하였다. 실험결과치로부터 총괄액상물질전달계수를 계산하였다. 실험은 Reynolds수가 220∼540, 온도가 5∼40 ℃의 제한된 범위에서 행하였다.
본 연구의 결과로서;
1. 총괄액상물질전달계수에 대한 온도의 영향은 다음과 같다.
KL（t） = KL(20.) 1.007(t-20)
2. 젖은 벽탑에서 실험결과치의 무차원 상관관계식은 다음과 같다.
ShL=83.89（Ref）0.0782(ScL)0.2607

The effect of temperature and liquid flow rate in the mass transfer of oxygen to liquid water in the wetted wall column was studied. The over-all liquid phase mass transfer coefficient were calculated from the experimental data. The runs were made over a limited range of Reynolds number 220 to 540 and temperature 5 ℃ to 40 ℃．
As a result of this study :
1. The effect of temperature on over-all liquid phase mass transfer coefficient was obtained as follow.
KL（t） = KL(20.) 1.007(t-20)
2. The dimensionless correlation of the experimental data in the wetted wall column was obtained as follow.
