| Abstract: | In the present paper, the 3D RANDS equations are solved on a three-dimensional hull body-fitted coordinate system by using the finite-analytic method and standard k-ε turbulent model with wall function, and a modilfied new SMIPLER algorithm is proposed to be used as an equal-order pressure-velocity coupling scheme. The three-dimensional viscous flow around a Wigley ship model in oblique motion is computed. Part of the present calculation results are compared with the existing results obtained by experiments and those from other theoretical approaches. |
