| Abstract: | The mesh for the T-shped junctions was generated using the multi-block techniques for analysing 3D complex flow fields. The incomplete Cholesky decomposition preconditioned conjugate gradient method and bi-conjugate gradient method were applied in solving the discretized govering equations. The calculation demonstrates that the methods used in this paper have good properties in convergence, and is worth recommended for the calculations of complex flows. |
