Simulation and Analysis of the Internal Flow Field of Mining Solenoid Pilot Valve Based on Fluent

Abstract

AbstractDuring the commutation process, the electromagnetic pilot valve experiences turbulent kinetic energy dissipation, leading to unstable internal flow and generating noise in the valve. Based on computational fluid dynamics (CFD), the phenomena of impact and energy consumption in a new type of high-pressure and high-speed electromagnetic pilot valve were investigated. Then flow field simulations were conducted under various differential pressure and valve opening conditions, in order to obtain distribution maps of turbulent kinetic energy, pressure, and velocity. Finally, the simulation results were compared, and the results showed that increasing the outlet pressure and enlarging the valve port opening have a positive impact on mitigating the structural issues in the pilot valve.
