This paper deals with numerical computation on viscous flows with free surface past a full ship hull such as a VLCC by using an improved Reynolds-Averaged Navier-Stokes solver with global conservation. I turbulence modifications in order to obtain the simulation of stern flow such as the hook shape of axial velocity n the previous report, we investigated the detailed computation of viscous flows with free surface by the modified Baldwin-Lomax turbulence model which was modified by introducing the two kinds of contours. The numerical computations were applied to a series 60 ship model. The numerical results were compared with measurement data and we showed the usefulness of this numerical scheme. In the present paper, this scheme is applied to the simulation of the viscous flows with free surface around SR 196 A, B and C of a large full ship type having slightly different frame lines in the aft half. We could show the difference of viscous flows around the aft half by the differences of frame lines of each ship model.
