Abstract

A 3D steady state numerical model for the oil-water dispersed flow has been discovered to study the impacts of shear stress on the dispersed phase behaviour in a pipe with vertical situation. CFD tool by ANSYS software is used to investigate the wall shear stress and water droplet pressure. The flow range for the continuous process was explained through the resolution of the Navier-Stokes conservation equations with k–β turbulence model are summed in Reynolds. A recent experimental method analysis was simulated. The geometry is 3.2 m long and 38 mm in diameter tube. Oil droplet width has been presumed to be dependent on flow Reynolds number and it has demonstrated numerically for this case of study. When the mixture velocity Um of1.5 m/s, the droplet diameter Dd was found 4 mm. Shear stress was developed by current work for a different number of velocities (1.5,2,2.5 m/s) at oil fraction (cut off) is 0.2 ,the simulation results show that, the greatest shear stress value was at the uppermost point of pipe and it was 69 Pa.
