Abstract:
The inviscid-viscous interaction is used to analyze the three
dimensional viscous flow in impellers in the present paper. The
semi-orthogonal curvilinear coordinates, the anisotropy eddy viscosity
turbulence model and Keller box method are used for calculating three
dimensional boundary layers on blade surfaces. The direct nonlinear
boundary element method is applied to calculate the three dimensional
potential flow in impeller passage. Calculated results are found in
agreement with measure values.
