Abstract

Fiberscope와 고속촬영기를 사용하여 교반조내에서의 액경분포를 측정하였다. 실험에는 크기가 다른 두 교반조와 두가지 형태의 서로 다른 크기의 네가지 교반날개를 사용하였고 물리적 특성치를 변화시키기 위하여 세가지 계를 사용하였다. 측정 액경분포로부터 bimodality analysis를 통하여 합체율을 추정하는 방법을 시도하였고 평균 액경을 계의 물리적 특성치와 조업조건의 함수관계로 나타내었다.
A fiberscope and highspeed camera system was employed to measure drop size distribution in a stirred vessel. Two geometrically similar vessels, two types of impellers were used for the experiment. Three systems were chosen for a variation of physical properties. With the measured size spectra, bimodality analysis technique was introduced to predict the coalescence ratio. Sauter mean diameter was correlated with operating variables and physical properties.
