Slug flow in Piping

[faisal99]

what is Slug flow in Piping................?

[Mohamed]

In Horizontal flow the general agreement is a division of eight categories of flow regimes. They are as follows: (Brown and Beggs)

1. Bubble flow
2. Plug flow
3. Stratified flow (layered, separated)
4. Wavy flow (ripple flow, cresting)
5. Slug flow
6. Semi-annular flow
7. Annular flow (ringed)
8. Spray flow (mist, froth, dispersed)

Slug flow




normal or hydrodynamic slug flow occurs at moderate gas and liquid flow rates and hence is commonly encountered in multiphase pipelines. The intermittent nature of this type of flow means that the separation plant at the downstream end of a slugging multiphase line will experience variations in liquid and gas flow.
To be able to design reception facilities to accommodate slug flow, and to design pipe supports to handle the forces associated with slug flow, it is necessary to predict both of the following:
· Slug volume (slug length and liquid content)
· Slug velocity
