Experimental Investigation of Slug Flow in a Pipe Subjected to Fluid Injection at the Wall
Abstract eng: The present work investigates experimentally the changes on the properties of horizontal gas-liquid slug flows subject to fluid injection at the wall. Measurements include data on global parameters including flow rates and pressure drop for ten different conditions. A Shadow Sizer system is used to determine the geometric and kinematic properties of the flow. Three flow transpiration rates are discussed, ++ vw = vw /Um = 0.0, 0.0005 and 0.001. The effects of flow transpiration induce bubble break-up and large changes in the passage frequency and characteristic lengths of unit cells. The work introduces modifications to single-phase wall injection models and unit cell models for gas-liquid slug flow to propose a unified theory capable of dealing with the effects of wall injection on slug flow. All theoretical predictions are compared with the experimental data.
