This paper presents the design optimization results for the anchor shape of the solenoid part of a flow-rate control valve by executing the design of experiments (DOE) for developing a quieter high-pressure pump. The impact of the noise level increases with an increase to the valve impingement velocity, so the objective of the design optimization is to reduce the valve impingement velocity. In this study, we executed the DOE to simulate two models of the anchor/core of the solenoid part of a flow-rate control valve, grooved and oblique, to optimize the anchor shape by varying four design parameters and then compared them with the original anchor/core design. We evaluated the anchor impingement velocity results with regard to the factor effects and clarified the relation between the velocity and the design parameters.
Key Words: Valve, Computational fluid dynamics (CFD), Solenoid, Impingement, Co-simulation, Optimization, Design of experiments (DOE)
