Abstract
The pump control valve is a butterfly valve that has an eccentric rotating axis. it is not only used as a butterfly valve to control the flow rate or pressure, but also as a check valve to prevent backward flow. A new design of eccentric rotating axis is proposed to design the valve. The height of the rotating axis is determined through flow field analysis. A general purpose of computational fluid dynamics software system, Fluent is used to simulate the fluid flow. Flow field analysis is performed for various heigts of the rotating axis and different opening angles of the valve. A characteristic function is defined for estimating the flow characteristics based on the results flow field analysis. The characteristic function is defined in order to determine the height of the rotating axis. An optimization problem with a characteristic function is formulated to determine the amount of eccentricity. The height of the rotating axis of the valve is determined through solving the optimization problem.
