With k- e turbulent model and wall function presented by Launder and Spalding, numerical results of viscous resistance coefficient, isoplethic maps of velocity and stress contributions areobtained.

采用k-ε紊流模式及Launder和Spalding提出的壁函数进行数值模拟，得到了该双尾船船体粘性阻力及速度、切应力的等值线分布等结果。

In this paper the viscous flows around a mathematical SWATH in full scale are simulated based on the computational fluid dynamics commercial software FLUENT. The numerical results of total pressure, wall shear stress and the corresponding viscous resistance coefficient at different velocity are obtained. The computational viscous resistance coefficients are compared with the estimated ones using empirical formula. The validity of the software to predict the three dimensional viscous flows and viscous resi...
