文摘The finite element method of computational fluid dynamics was applied to simulate the internal flow field in hydraulic spool valve which is one of the most important components in hydraulic technique. The formation of the vortexes with time was investigated under two different flow conditions. Two kinds of flow descriptions including streamline patterns and velocity vector plots were given to show the flow field inside the spool valve clearly, which is of theoretical significance and of practical values to analyze energy loss and fluid noise in the valve and to optimize the intermal flow structure of the valve.
