Turbulent model in 2D calculations

Flow community: Question: What is the validity of using turbulent models in 2D calculations? I use the k-epsilon standard model of fluent with the law of the wall in a curvilinear profile which contains 2 or 3 stirring blades. Using the MRF (moving reference frame) model I obtain a general velocity vector diagram on a plane for my domain. This compares rather well with flow lines, I observe in a tank. In the model, I input a value for the angular velocity (omega). When I look at the equations of motion all the components involving the z derivative and values of w are equal to zero. How can I explain, the fact that I am solving for 2D but it seems that all the centrifugal term and the coriolis term seem to go to zero. I conclude the program takes a constant value for Z. Is this correct? Does any body know this in fluent?
