Abstract
Hydraulic spool valve is one of the important elements in the hydraulic system. Considering the material properties of the fluid and solid, CFD models of the viscous temperature rise was built and calculated with the spool material influence on the viscous temperature rise and thermal deformation. Analyzed: the viscosity of the fluid was the main factor affecting on temperature rise, while the coefficient of thermal expansion of the spool was also the main factor to affect the throttling temperature rise of the deformation.
