Abstract: Inertia items in Navier-Stokes equations are often ignored
in design of hydrostatic bearing for sliding shoe of oil hydraulic axial
piston pump because it is much less than viscosity items and has little
effect on computing results. However, in research of water hydraulic
axial piston pump, inertia items should play an important role because
the viscosity of water is much less than that of oil. The effect of
water flowing inertia on the distribution of pressure and velocity in
the bearing clearance is studied, water hydrostatic bearing design is
revised and more feasible results are drawn.
