When the Navier-Stokes equations are time averaged, we can treat the flow as two-dimensional (if the geometry is two-dimensional) ?

Read from: Page no: 68 of "http://www.tfd.chalmers.se/~lada/postscript_files/solids-and-fluids_turbulent-flow_turbulence-modelling.pdf" that "...Turbulent flow is always three-dimensional and...

Initializing the domain with standard type, for multi-phase flow, is computing velocity wrongly. Can anyone suggest a reason for this?

In fluent when i initialize the solution with standard type for multi-phase flow, the velocity computed by Fluent is wrong. I am using mass flow inlet type boundary.
