Abstract
본 연구는 액-액 물질 이동계에서의 계면난류에 관한 연구로서 tributylphosphate（TBP）-ethanol(EtOH)-sodium hydroxide계에서 TBP-에탄올의 혼합비와 액적의 직경을 변화시켜 계의 물리화학적 특성과 계면의 유체역학적 특성을 변화시키면서 이에 따른 Marangoni효과와 미소교란해석(small disturbance analysis)에 의한 불안정 조건을 분석 검토하였으며, 이때의 물질이동계수를 무차원수 Sh, Sc, Mo 및 Jo와 다음과 같이 상관시켰다.
In the present work the interfacial turbulence of a tributyl phosphate （TBP）-ethanol (EtOH)-sodium hydroxide system was analysed through small disturbance theory and interfacial instability conditions in the viewpoint of Marangoni effect according to physico-chemical and hydrodynamic properties which were varied with the volume ratios of TBP to ethanol and drop diameters.
The interfacial instability conditions was discussed in terms of the critical Marangoni number and the mass transfer coefficients were correlated with dimensionless groups of Sh, Sc, Mo, and Jo as follows :
