Ahh I see. I thought the solver would have internally scaled the mass flow inlet BC to the fully revolved case in the back end. I didn't have to scale the inlet BC for the 2D axisymmetric case!

Thank you so much this was helpful- I am now getting results that I am expecting!

For future readers who were stuck like me: I divided my mass flow inlet BC value by 4 because the inlet area was 1/4 of the fully revolved area. So for periodic BCs, you need to scale your mass flow inlet value relative to the inlet face area that you start with.Â
