摘　　要：利用 TASCflow3 D求解了带导管轴对称体的三维不可压缩粘性湍流内外粘性流场的绕流问题 ( Re=5 .6× 1 0 6 )。基本求解器控制方程为 RANS方程 ,并使用了标准 k-ε封闭模型。离散化用有限元方法描述几何图形的有限体积法 ,既保证了有限元描述几何体的灵活性 ,又保证了有限体积法的守恒特性。利用多块代数多重网络技术加快收敛速度 ,使其求解实际工程中复杂几何体绕流问题能力大大增强。数值结果与试验进行了比较 ,表明本方法收敛性态良好 ,适用性强 。In this paper, TASCflow3D is used to solve inner and outer 3 D viscous incompressible turbulent flow(Re=5.6×10 6) around an axisymmetric body with a duct. Governing equation is RANS equation with standard k ε model. The discrete method is a finite volume method based on a finite element approach of representing the geometry, thus the method retains much of geometry flexibility of finite element method as well as the important conservation properties of the finite volume method. The capability of the solver is greatly enhanced through the use of the Multiblock and Algebraic Multigrid techniques to solve realistic problems with complex physics over complex geometries.The numerical result is compared with experiment and the agreement between them is good. It shows that the present method is effective.
