Flow characteristics of butterfly valve by PIV and CFD
Butterfly valves are widely used as on-off and control valves for industrial process. The importance of butterfly valves as control valves has been increasing because the pressure loss is smaller than other types of valves and compactness is very desirable for installation. These features are desirable for saving energy and high efficiency of instruments. Butterfly valves have been adopted in modern industrial fields of a water supply plant, cooling plant for nuclear power station, the petrochemical industry, marine industry and so on and the hydrodynamic characteristics of butterfly valves have been actively studied in terms of the pressure loss. This study has focused on the investigation of the detailed hydrodynamic characteristics to compare analysis results by PIV and CFD. As comparison of both analyses by using water, vector velocities, pressure distributions, kinetic energy contours, ow coefficient and pressure coefficient indicated the similar characteristics pattern during the course of this investigation.
