Application of CFD in Hydraulic Directional Valve Modeling
Abstract:
The paper considers the task of using computational fluid dynamics in order to upgrade a hydraulic directional valve, which works in mining powered roof support. The modernization is focused on changing the design parameters of the valve so as to reduce pressure drop and thus increase its capacity. In addition emphasis was placed on verifying the simulation results in transient states with the results obtained on the research station.
