Slugging the pipe
Webb1 aug. 1990 · Severe slugging, characterized by generation of slugs ranging in length from one to several riser pipe heights, occurs at low gas and liquid flow rates and for negative … In fluid mechanics, slug flow in liquid–gas two-phase flow is a type of flow pattern. Lighter, faster moving continuous fluid which contains gas bubbles - pushes along a disperse gas bubble. Pressure oscillations within piping can be caused by slug flow. The word slug usually refers to the heavier, slower moving fluid, but can also be used to refer to the bubbles of the lighter fluid.

It is characterized by large pressure and production fluctuations. One of the ways of suppressing or eliminating fluctuation due to slugging is by choking.
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. Webb1 sep. 2006 · Design target unit piping to include bypass systems that allow gradual heating and pressurization on startup. 6.
