Numerical Simulation and Visualization of Flow Field in a Special Piloted Directional Valve for Marine Steering Gear
In order to understand the working performance of the special pilot operated directional valve, flow field simulation based on CFD and dynamic response simulation in MatLAB Simulink are adopted in the study of this paper.3D flow field model of the valve with three kinds of the notch separately is build up using Pro/E, Gambit is used to generate quality computational grid, and the numerical simulation is performed by using the commercial code Fluent.The mathematic model based on physical equations for the valve is also established in Matlab Simulink, the dynamic responses are analyzed for the valve with three different notch types separately.The results show that the minimum pressure positions in flow fields are on the valve body near the notches.The value of the minimum pressure with K notches is the highest among three kind notch types.The minimum pressures will decrease greatly along with the flow rate increased.The efflux angles for the valve with three kind notch types separately are different, so are the steady flow forces.The valve with V notches responses quickest, but the ram moves quickest with U notch valve.The research in the paper contributes to a deeper understanding of the flow and dynamic response characteristics.The research method combining CFD simulation and MatLAB Simulink is available and will derive more precise results.
