Abstract

The primary purpose of this study is to investigate the pressure effects on liquid and gas slugs in the plug flow regime. In this study the pressure in the closed-loop system was changed from 0.3 to 20MPa at a constant fluid temperature on horizontal flow. The point of disappearance of the liquid slug, mean lengths of gas and liquid slugs, and the frequency distributions of gas and liquid slug lengths were measured to investigate the characteristics of plug flow. The approximate experimental equation for the mean length of the gas slug and the point of disappearance of the liquid slug is presented.
