Abstract

분사에 의하여 만들어진 거품의 초기기포크기 분포를 발표된 분포식들과 비교하였다. 기포크기 분포의 변화에 대하여 기체확산을 고려한 모델식으로부터 얻은 계산치와 실험치가 서로 잘 일치하는 것을 확인하였다. 아울러 거품의 표면적 감소와 평균기포반경의 변화에 대한 초기기포크기 분포의 영향을 검토하였다.

The intial size distribution of bubbles in a foam prepared by sparging technique was compared with the proposed distribution functions. It was confirmed that the data on the change of bubble size distribution were in good correlation with the results obtained from the model equation based on the interbubble gas diffusion. The effect of the initial bubble size distribution on the decrease of the surface area and the change of mean radii were also discussed.
