Slug flow experiments and computer simulation of slug length distribution in vertical pipes
- Univ. of Toronto, Ontario (Canada). Dept. of Chemical Engineering and Applied Chemistry
Experiments on air-kerosene developing slug flow in a vertical pipe were conducted and the slug length distribution in vertical pipes was also simulated using a computer code. The aim of the experiments was to investigate the effect of flow parameters on the bubble rise velocity. The rise velocity of the trailing bubble was found to increase with its size while the size of the leading bubble was found to affect its wake length, and therefore, the point at which the trailing bubble starts to accelerate. The bubble rise velocity data were correlated in terms of the separation distance between the leading and the trailing bubbles. A computer model was developed to simulate the slug length distribution in vertical pipes. The model was based on the bubble overtaking mechanisms in which the trailing bubbles would catch up and merge with the leading bubbles. The computer model was able to predict reasonably accurately the liquid slug length distributions at the outlets given a specified inlet liquid slug length distributions.
