Hello everyone. (1)In the angle view of cfx-bladegen, the M-Prime on the abscissa represents the ""radius"" normalized distance along the meridional curve. I don't know what the "radius" represent. could anybody tell me about it in detail or some references about the "radius normalized meridional distance" . Thanks in advanced!

If you plot blade-to-blade surface in dimensional R*Theta-M view, the distance between blade will increase with radius. M' is defined as M/R. Now blade angle will be preserved in Theta-M' view.
