This paper deals with the calculations of the viscous flow over the stern and in the wake of a practical full hull form, the Ore Carrier SR107. The purpose of this paper is to examine the accuracy of the calculations at a high Reynolds number (Re=1.2×10^7) by comparing calculations and experiments. The calculations were made at the University of Iowa by solving the Reynolds-averaged Navier-Stokes equations, and the experiments were carried out at the Nagasaki Experimental Tank, Mitsubishi Heavy Industries. This paper also deals with the Reynolds number effect on the stern flow by comparing the results calculated and measured at two Reynolds numbers (Re=1.2×10^7 and 2.4×10^6). The results of this study may be summarized as follows: (1) Good agreement between calculations and experiments is obtained in the wake distribution. (2) A thinner boundary layer and a stronger bilge vortex are calculated at higher Reynolds number than those in the case of lower Reynolds number. This tendency agrees with experimental results. (3) The calculated bilge vortex is relatively weak compared with that observed in the experiments.
