I have a very basic question. In the axial turbine example in the CFX tutorial, the rotor has 113 blades and the stator has 60 blades. The blade row is scaled with the factor of 0.942 (using two blades and one vane). However the blade row is not actually scaled, since the total number of blades used, based on which the flow passage is created, are still 113 while I expected it to be approximated to 120! Could anyone be so kind to explain this to me?
