CALCULATION OF 3-DIMENSIONAL INCOMPRESSIB LE VISCOUS-FLOW IN TURBOMACHINERY ROTORS

A numerical method for calculating three-dimensional incompressible vi scous flow in turbomachinery rotors is described. A finite-volume disc retization for the conservation equations for mass and momentum and th e equations of the k,epsilon-turbulence model is used to produce linea rized systems of equations. The SIMPLE algorithm is adopted to calcula te the pressure and to enforce mass conservation. The equation systems are solved with the strongly implicit procedure. Results in the rotor and the wake region of an axial compressor rotor are presented and co mpared with measurements.
