Simulation results of the flow fields created by the translational motion of the left ellipsoid. Black arrows describe the local flow direction. The color represents the local flow speed u in the x direction. p=1.8 in panels (a), (c), and (e), and p=7.5 in panels (b), (d), and (f). X/2a=1.05 in panels (c) and (d), and 3.4 in panels (e) and (f).
