| Abstract: | Based on a multifunctional CFD software, thethree-dimensional velocity field within the impeller of NASA low-speed centrifugal compressor is computed in detail in this paper.Detailed quantitative analysis is then carried out through comparing the results with experimental data as well as the results from another CFD software. Moreover, the ability of CFD sof ware to predict the flow field inside the impeller and the existing problems are studied. Suggestions are given to further improve numerical computation precision. |
