摘要：

Turbulent separated flows around ellipsoids of various aspect ratios are investigated using a numerical method. The Reynolds averaged equations for continuity and momentum are solved by cell-centered finite-volume method for the primitive variables to describe the 3D turbulent incompressible flow. The objectives of the study are: (a) to investigate the propulsive performances of a moving Remotely Operated Vehicle (ROV hereafter) ellipsoidal body; (b) to validate the computational solutions through comparisons with the experimental data; (c) to investigate the effects of the angle of attack on the separation pattern as well as on the hydrodynamic forces and moments.
