ABSTRACT

High performance rotors and narrow design margins for future turbomachinery demand accurate flow analysis methods and design products. With the advance of computational power, numerical methods that solve the Reynolds averaged Navier-Stokes equations not only provide detailed flow analyses but become an important element of turbomachinery design. In this paper, we use a Navier-Stokes solver first to analyze a rotor clearance flow for a single-stage stator-rotor pump and then to integrate this calculation method with a design procedure that was applied to a series of rotor-stator fan designs.
