摘要：
A theoretical model for bubble formation and weeping has been developed. Potential flow theory is used to describe bubble formation at the orifice. The influence of detached, rising bubbles on liquid pressure at the orifice is predicted by Oseen's modification to potential flow. Model predictions of bubble volumes, weeping flow rates and weep points agree well with experimental results. (C) 2000 Elsevier Science Ltd. All rights reserved.
