인산-옥탄올-물 삼성분계에서 액적내부의 물질전달
Mass Transfer inside Drops in the Ternary System of Phosphoric Acid, n-Octanol and Water
초록
액적의 유동상태와 농도에 따른 물리적 특성이 분산상의 물질이동계수에 미치는 영향을 인산-옥탄올-물 삼성분계에서 실험적으로 고찰하였다. 상승하는 동안 액적의 유동상태는 전 실험범위에 걸쳐 진동과 wobbling현상을 보였다. 본 실험범위에서 분산상의 물질이동계수를 무차원 해석한 결과 아래의 상관관계식을 얻었다.
Shd = 0.117Ped0.71(μc/μd+μc)0.92
Shd = 0.117Ped0.71(μc/μd+μc)0.92
The effects of drop dynamics and physical properties on the dispersed-phase mass transfer coefficient were studied experimentally in the ternary system of phosphoric acid-n-octanol-water.
In the present experiments, the drops showed oscillation and wobbling during the rising period. Using the experimental results, the following dimensionless correlation was produced for representing the dispersed-phase mass transfer :
Shd = 0.117Ped0.71(μc/μd+μc)0.92
