 December 20, 2003, 08:24 What is Pitch?? #1 Anne Guest   Posts: n/a Hi All, I am starting to use the CFX5.6. I need to understand the concept of pitch. The CFD5.6 documentation refers me to the Example on Rotor Stator. I have read and run this but I still do not understand. I have got very little (if not zero) Mechanical Engineering background. I am running my transient simulation now and I can see pitches increasing with time step but I am not sure of the implication of this. Please help. Regards Anne

In simple terms, it is the size of the pie slice. A pizza sliced into 10 pieces has a pitch of 1/10, whereas a pizza sliced into 12 pieces has a smaller pitch, 1/12. MMmmm, Pizza :-P When you run a transient rotor stator problem, the pitch you see increasing is the offset of the domain from its initial location, i.e. how far it has rotated about the axis.
