The Transient Characteristics of Oil Pipelines with Column Separation

抄録

In this report, the phenomena on an oil column separation resulting from a sudden decrease of the pressure or a flow at the end of various pipeline systems are reported. The main contents are as follows: (1) The theoretical solutions for the occurrence limits of the column separation are derived. Agreement between the calculated values and the experimental ones is good. (2) The photographs of cavities formed by the column separation are taken, and the cavity behaviours are explained. (3) The pressure surge resulting from a collapse of the cavity also is recorded.
