Boundary Condition for 2D simulation of Turbo-machinery

This is first time i am doing a 2D analysis, since 3D un-steady analysis will involve huge computational time.
I am planning to do a 2D un-steady analysis to simulate the effect of on-coming wakes on LPT Vane boundary layer and blade loading by using Fluent. For simulating wakes I am using cylinder upstream of LPT Vane(picture enclosed).I have the following queries
1. What should be the boundary condition for LPT Vane Edges which I have marked with red line, if I am doing a 2D analysis how does I specify periodicity (rotational) or does it is required.Edges with black line are for inlet and outlet.
2. Same is for the hole mesh.
3. Does I have to do a axi-symmetric analysis or 2D planar.
I have attached two mesh pics one that of hole and other one for LPT Vane.
Thanks in advance for your valuable input.

If I understand correctly, I guess you will do a sliding mesh and have a moving wake pass through?
You would not be able to do this in an axissymmetric simulation. This looks to be 2D-planar. I wonder if there is some cute transform or option to make it 2D-curvillear but I do not know off the top of my head.
