Abstract:By means of a flow rate equation, the boundary layer is closely connected with the core flow and can be computed into separated region continuously. In the model, the Stanitz rapid approximate method is used to determine the inviscid potential flow, and an integral method is presented to evaluate the two-dimensional incompressible turbulent boundary layer with rotation and wall-curvature. The procedure can be easily and rapidly used to evaluate the flow with positive incidence angle in a centrifugal impeller.
Keywords:centrifugal impeller  off-design condition  turbulent boundary layer  separation
