Abstract :

Numerical simulation of flow through two types of valves namely dual plate check valve and butterfly valve has been made for various opening conditions. The commercially available software package of ANSYS FLUENT is used for this purpose. Methodology is validated by using K-ɛ model by analyzing the developing flow through circular pipe. The geometry has been idealized as two dimensional in the view of the limitations of available computational facilities. The value of pressure loss coefficient (CP) and drag force coefficient (CD) has been evaluated at various openings and Reynolds number. It is observed that value of pressure loss coefficient (CP) and drag force coefficient (CD) lower in case of dual plate check valve. The effect of fillet radius on the outer edge of the valve disc also been analyzed and it is observed that significant reduction in CP and CD can be achieved by smoothing of the outer edge of the valve disc. The pressure drop characteristics of two types of valve have been compared at different angles of opening and Reynolds number. The detached flow pattern at various operating conditions is presented in the form of velocity vector plots. This reveals that the energy loss due to separation is less in the case of dual plate check valve.
