In the panel Shaft, the required shaft diameter is computed.

¢ Shaft/ Hub

 

The hub diameter has to be determined in the panel Main dimensions.

 

The main dimensions of a designed rotor - suction diameter dS, impeller diameter d1, outlet width b1 - can be seen on the tab sheet Dimensions. They can be recomputed by pressing the Calculate-button within the panel Main dimensions. The computation is based on "Euler's Equation of Turbomachinery", on the continuity equation and the relations for the velocity triangles as well as on the parameters and parameter ratios given in the tab sheets Design Point and Parameters.

 

One may accept the proposed values or can modify them slightly, e.g. to meet a certain normalized diameter.

In case the checkbox Automatic is activated a new calculation will accomplished after any change of parameter. Then the manual alteration of the main dimensions is not possible.

 

 

In the right panel of any tab sheet an information panel is situated, which holds the computed variables in accordance to the actual state of design, the resulting Meridional section as well as the Cordier-Diagramm with the location of the best point. These three sections can be chosen by the appropriate soft buttons in the heading.

 

In the information section of the tab sheet Dimensions the following variables are displayed for Information:

 

 

The guidelines given in the last column of the last three rows, should be be matched within the design.

 

The Meridional section is based on the main dimensions designed until this point.

 

 

The Cordier diagram is based on an intensive empirical analysis of proved turbomachinery using extensive experimental data..
