3D SIMULATION OF FLOW PROFILE (OIL AND WATER) SUPPPORTED WITH ANALYTIC ESTIMATIONS OF PRESSURE DROP AND SHEAR STRESS

In this article, core annular flow (CAF) simulation was made between oil and water in a circular horizontal glass tube applying two-phase laminar level-set method. Experimental values of oil/water inlet velocities and cuts (oil or water volumetric ratio) were used for the simulation. At those conditions, plug flow was predominantly observed. Numerically, in order to adjust from plug to CAF flow profile, the oil/water cuts and velocities were adjusted. The numerical method was validated by reproducing the volume flow.
