The designed geometry can be extended in meridional direction at the outlet.

 

 

The extension defines the Rotor-Stator-Interface (RSI). Its geometric parameters will be considered at the next component as inlet conditions so that the geometries as well as the meshes based on them match each other. Typically, the RSI is located in the middle of the rotating and the non-rotating component.

The use of the extension is recommended, because otherwise the trailing edges of the blades would just lie on the rotor-stator interface, which can cause both meshing problems and numerical simulation errors. Meshing problems could occur, especially for small values of the blade angle ß2.

 

For unbladed stators, the extension is not necessary and therefore not activatable.
