Abstract
The present work carries out experimental work on horizontal slug flows subject to fluid injection at the wall. Data include results on flow rates and pressure drop for ten different conditions. The properties of the two-phase flow are measured through a Shadow Sizer system. Two distinct flow transpiration rates are studied, v++ w = vw/Um = 0.0005 and 0.001. The effects of flow transpiration were observed to provoke bubble break-up and large changes in the passage frequency and characteristic lengths of the unit cells. The work suggests changes in the models for slug flow so that fluid injection at the wall can be accounted for
