摘要
The variations of ship stern flow field structure and its corresponding hydrodnamic performance under full scale Reynolds numbal (5 109) and model scale Reynolds numbal(5 106) are investigated numerically in this paper. The governing equations for 3-D incompressible turbulent flow which consist of RANS equation and K-ε two equation turbulence model are solved by finite difference scheme. Derailed computational results are presented graphically. The comparisons between present calculation, existing measurement and other calculation are made.
