Abstract
The flow with movement of single slugs in an annular channel was studied. The shear stress on both walls of the annular channel was measured using the electrodiffusion method. The averaged wall shear stress distributions along the channel length during gas slug motion are presented for different regimes. A significant difference in the values of shear stress on the inner and outer walls of the channel is shown.
