The internal flow fields of liquids in space between casing and rotating disk have been obtained by using CFD.The curves of shear stress on the disk and static pressure on casing wall against radius are also gained in various viscosity and different leakage conditions.The results indicate that the shear stress is influenced significantly by the leakage in the space.The shear stress on the disk decreases with the increase of leakage,especially in small radius.However, the reduction rate of stress gets smaller with the increasing of liquid viscosity.The greater the viscosity is, the higher the shear stress is.The growth of shear stress along the direction of radius is greater than in small viscosity.

We can find that the mesh adopted by CSD and by CFD is quite different.
Thus, if the effect of interpolation is not improved, the numerical simulation precision will be directly impacted.
