t, m conformal mapping

Previous pageReturn to chapter overviewNext page

The spatially curved meridional flow surfaces are mapped to a plane by coordinate transformation. This coordinate system has the angle in circumferential direction t as abscissa and the dimensionless meridional extension m as the ordinate.

Both quantities are created by the reference of absolute distances in meridional (M) and tangential direction (T) to the local radius r:

Special display option for splitter blades:
With "Splitter blade relative to main blade" checked, corresponding mean lines (splitter and main) have the same maximum m-value. Otherwise all mean lines have the same maximum m-value as the main blade's hub mean line.
