We are trying to simulate an assembly of axial turbine which consists of upstream guide vane followed by a rotor followed by a downstream guide vane. We were providing the inlet boundary conditions at the inlet of upstream guide vane and outlet at downstream guide vane. Our results are not up to the mark.

We have a query, instead of providing the outlet boundary conditions to the outlet of downstream guide vane, can we provide it at the exit of the rotor stage? If so, how do we do it.

You will have to remove the EGV's for that. U can't have a BC in middle of ur domain, ( hence BOUNDARY condition :P )

There might be more than one reason for ur mismatch of results, Simplifying the geometry might or might not help.
