The numerical method which is based on flux difference splitting, LUdecomposition, and implicit high-resolution third-order Essentially Non-Oscillatory (ENO) scheme wasconstructed for the efficient computation of steady state solution to three-dimensionalincompressible Navier-Stokes e-quations in general coordinates. The flowfields over underwateraxisymmetric bodies, full-appended axisymmetric bodies and axisymetric bodies with a ring-wing ductwere simulated. The method is proved to be capable of predicting the circumferential-mean velocitydistribution at model scale to the accuracy of around 3% of measured values, and of predicting somedetails of flow features, for example, the wake harmonics. 展开更多
