Abstract

불균일상의 액-액 계면을 통하여 전달되는 용질의 물질전단계수를 개량된 Lewis cell을 사용하여 측정하였다. 수용액상의 측정치 Sherwood수, Sh₁를 수용액상의 Reynolds수, Re₁, Schmidt수, Sc₁, Capil-lary수, Ca₁, 유기상의 Reynolds수, Re₂ 및 점도 보정치, Φ등과 같은 실험변수들을 사용하여 관련지었으며, 평균편차 15.3% 이내에서 다음과 같은 상관관계식을 얻을 수 있었다._x000D_ Sh₁=0.0194Sh₁^1/3 Ca₁^6/13[Φ⁴Re₁³+Re₂^8/3]^1/4

The mass transfer coefficients of a solute through a flat interface of partially miscible binary systems were obtained in an agitated vessel of a modified Lewis cell type. The observed Sherwood number for an aqueous phase, Sh₁ were correlated in terms of the aqueous Reynolds number, Re₁, Schmidt number, Sc₁, Capillary number, Ca₁, a function of viscosity ratio, Ø and the organic phase Reynolds number, Re₂. The correlation among these variables represented with an aberage deviation of 15.3% as the following equation._x000D_ Sh₁=0.0194Sc₁^1/3Ca₁^6/13[Ø⁴Re₁³+Re₂^8/3]^1/4
