WebbSlugs can be generated by different mechanisms in a pipeline: Terrain slugging is caused by the elevations in the pipeline, which follows the ground elevation or the sea bed. Liquid can accumulate at a low point of the pipeline until sufficient pressure builds up behind it. Once the liquid is pushed out of the low point, it can form a slug.

Severe Slugging in Offshore Pipeline Riser-Pipe Systems

WebbOne of the methods for calculating the effect of slug flow loads is the static method. Vertical, horizontal, and resultant forces F can be determined by the formulas: where. θ – bend angle (90 degrees, 45 degrees, etc.) ρ – fluid density. v – slug velocity at the moment then it hits the bend. A – internal pipe cross-section area. Webb2 dec. 2024 · Slug forces are generated when there is 'two-phase' (gaseous and liquid phase) fluid flowing through pipes and slugs of liquid that are formed intermittently travel at relatively high velocity. The liquid slug can cause large reaction forces at changes in direction such as elbows or tee connections. biotin dr axeWebb1 feb. 1985 · Abstract. Severe slug flow (i.e., terrain-dominated slug flow) was studied in a simulated offshore pipeline riser-pipe system. Severe slug flow is characterized by extremely long liquid slugs generated at the base of the vertical riser.

This flow is characterised by the intermittent sequence of liquid slugs followed by longer gas bubbles flowing through a pipe.

Webb17 maj 2024 · Slugs formed by terrain slugging, hydrodynamic slugging or riser-based slugging are periodical in nature. Whether a slug is able to reach the outlet of the pipeline depends on the rate at which liquids are added to the slug at the front (i.e. in the direction of flow) and the rate at which liquids leave the slug at the back.
