Numerical Analysis on Ambient Flow of Axisymmetric Body

The three-dimensional steady Reynolds-averaged N-S equations were solved numerically by a finite volume method and applied to study the flow around three-dimensional axisymmetric body. The finite volume equations were formulated in strong conservative form on a general, non-orthogonal grid system. The mixed differencing scheme was used to form the differencing equations. Only a part of the convection flux and diffusion terms were treated implicitly to improve the stability of the iterative solution procedure.Numerical predictions of the turbulence were obtained with the κ-ε model. The resulting equations were solved by pressure correction allgorithm. The calculation results are presented in this report and compared with experimental data.
