Slug flow regime in a flowline with U-shape riser

A suitable initial point for understanding multiphase flows is a phenomenological description of the mechanism geometric distributions or flow patterns that are observed. The challenge however prediction combination operating conditions and characteristics phases as well points transition from one pattern to other. Different occur in different pipeline configurations which U-shape risers part. In quest stabilise unstable slug riser, an experimental study gas-liquid mixture conducted understand behaviour riser. This paper seeks dynamics 2-inch internal diameter riser system with much emphasis on flow. initiation this instabilities impact downcomer investigated experimentally. Understanding could help developing effective control techniques flowlines. Experimentally, observed configuration used develop regime map was then compared literature similarly purely vertical similar pipe diameter. Thus, envelope developed identify regions slugging system.
