Numerical Simulation of Barite Sag in Pipe and Annular Flow

Figure 13

3D visualization of the apparent barite accumulation on the lower side of a fully eccentric annulus (horizontal configuration) at = 0.1524 m/s, = 0 rpm (a), redistribution of the barite particles into the flow stream at = 0.1524 m/s, = 50 rpm.
