The method of flow regime prediction for gas-liquid mixtures (GLMs) in pipelines of different orientation, from horizontal to vertical, is described.
Formulas are presented for finding and plotting zone boundaries of individual GLM structures for flow regimes forming in pipelines under various operating conditions.
It is pointed out that when correspondence between flow regime and corrosion damage to the pipeline is properly established, the corrosion patterns and rates in a specific pipeline can be predicted with the help of this method on the basis of predetermined GLM structures.
