抄録

Numerical simulations of three dimensional flow in a spool valve have been made to investigate the flow force acting on the spool. The spool valve adopted here was practical hydraulic type having non-axisymmetrical flow paths with inlet and outlet ports located near the valve orifice. The flow field around the valve orifice was numerically simulated by a quasi-direct simulation based on the finite volume method using a co-location grid. The flow patterns around the spool such as jet angle, reattachment point of jet and vortices generated downstream the valve orifice were found to be non-axisymmetric. The distribution of momentum flux in the azimuthal direction at the valve orifice was strongly influenced by the flow separations at the edge of inlet port and the surface of spool. The non-uniformity of the distribution became mitigative with decreasing the spool stroke.
