| Abstract: |
| A dividing method of block structured grid of two level is proposed for the numerical simulation of the twist flow field in Kenics static mixer.When the similar grid quantity is gained for two dividing methods, the block structured grid of two level and common unstructured tetrahedral grid, the iterative accuracy of block structured grid of two level is one higher grade than the unstructured grid and the convergent time for the former is only 80% of the latter.The evaluation of the grid quality between two methods is carried based on the cell volume change.The grid quality index 1.0~2.0 is used for evaluation, 99% for the level of block structured grid and only 60% for common unstructured tetrahedral grid.The simulation results for the two methods are compared based on the experiment results.It shows that the simulation results from the structured grid agree with the experiments results well.The feasibility and accuracy of structured grid are better than the unstructured tetrahedral grid method. |
