This paper concerns the aerodynamic performances of parallel and opposed-blade dampers for regulating air volumes of duct systems. Previous papers show that an opposed-blade damper is appreciated more favorably than a parallel-blade damper in view of less possibility of uneven flow aft of blades and the controllability of pressure drops for duct systems. We have already examined them in detail by using the laminar flow analysis by FEM and flow visualization experiments. This paper studies on the aerodynamic performances of dampers based on turbulent flow analysis and compares with our previous results.
