Abstract
The main task in aerodynamic design of turbomachines is to create an an-
nuhis and to define the turning of blades and vanes which in turn fulfils
the performance requirements. The design process of multistage turboma-
chines is usually based on a quasi-three-dimensional model, which consists
of coupled two-dimensional representations of the flow in the hub-to-tip and
blade-to-blade plane respectively.
The aerodynamic model used here is based on the calculation of the
viscous flow along a streamplane of the meridian flow, which is represen-
tative for the pitch. The impact of three-dimensional effects and radial
mixing on the circumferential averaged flow properties are taken into ac-
count with the aid of models for secondary flow and cor
