Turbulent Flow Through a Transition Duct
 

Turbulent flow of air through a duct is computed for this benchmark. The cross-sectional planes of the duct transition from a circle at the inlet to a rectangle at the outflow boundary. The Reynolds-Stress Model (7 equation) is used for computing turbulence.
