This work aims on analyzing the flow characteristics and pressure variation upon flow of air across the a venturi with a butterfly valve setup. The valve is placed before the converging end and after the diverging end of the venturi. The flow is analyzed for different angular positions of the butterfly valve. A series of analysis for both normal venturi flows without the valve arrangement and with the valve are carried out to arrive at a conclusion of the effect of introducing the valve. The analysis is carried out in commercial ANSYS software assuming a two-dimensional flow. (Abstract) Keywords— Butterfly valve, venturi, flow velocity, turbulence

Numerical investigation of flow though venturi for various angular positions of the butterfly valve
