► Rotor | Main dimensions 
The Main Dimensions menu item is used to define main dimensions of the axial rotor. Main Dimensions are forming the most important basis for all following design steps.

The real flow in the impeller/rotor is turbulent and three-dimensional. Secondary flows, separation and reattachment in boundary layers, transient recirculation areas and other features may occur. Nevertheless it is useful - and it is common practice in the turbine design theory - to simplify the realistic flow applying representative streamlines for the first design approach. Employing 1D-streamline theory the following cross sections are significant in particular: •inlet (index 1) •outlet (index 2) |
