... ABSTRACT A set of air and highly viscous oil experiments was conducted to analyse the inner flow field of slug flow for low mixture Reynolds number conditions. The unsteady behavior of the wall shear stress profile was measured, modelled, and compared to an existing model. The Constant...

... and sensitivity studies to identify critical locations with risks of high shear stresses and water holdup. Through corrosion risk assessment, we narrow down the critical locations to four primary locations which, following direct inspection, could provide the information necessary to estimate the overall pipeline...

..., wall shear stress, Reynolds number, and radial temperature gradient. It was observed that paraffin deposition is not only dependent on the thermal driving force which is the temperature difference between oil bulk and initial inner pipe wall but also on turbulence effects. It was experimentally shown...
