Fig.1.3D model of air cooled condenser Fig.2.Layout of steam duct of air cooled condenser Fig.3.Semi-model for CFD analysis Fig.4.Grid configuration and layer mesh of steam duct Solution Algorithm The steam flow is modeled as an incompressible, turbulent and single phase flow.
Turbulence modeling and grid generation are dominant factors that affect the ability of CFD to accurately predict flow treatment.
No-slip velocity condition is applied to all walls and for simulation flow field near the walls “enhance wall treatment” is set.
The CFD analysis of the steam duct shows that the flow detaches from the wall shortly after the inlet to the conical section in the main duct.
