Description: ABSTRACT The paper presents a numerical simulation and analysis of the flow inside a hydraulic poppet valve and hydraulic control valve. This paper summarizes the successful application of Computational Fluid Dynamics (CFD) analysis to study the effect of spool slot configuration on spool and cavitation generation inside both the poppet valve and control valve. The hidrodynamic field inside in the valve can be modulated with good accuracy. Computational Fluid Dynamics (CFD) tools are evaluated for use in industrial design applications by predicting primary control valve performance characteristics. The performance parameter of primary interest to the manufacturer is the flow coefficient Cv. In addition, the study demonstrates the usefulness of simplified CFD analysis for relatively complex 3-D flows.
