| Abstract: | This article adopts the flow model of 2-D non-compressible ideal flowing and turbulent flowing boundary layer to compute the internal flow field for a multiblade fan,while potential flow speed for meridian plane and rotational plane uses integrated method;the blade boundary layer uses finite element method to find out resolution and uses Richardson number to reflect the effect of the rotation and curvature on the boundary layer structure.It shows that the accuracy of this computation method is more ideal through the example computation and comparison with experiment data. |
