► Impeller | Main dimensions

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

The real flow in a compressor impeller 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 compressor 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:

suction area/ inlet (index 1)

leading edge (index LE)

discharge side/ outlet (index 2)
