    Abstract：The UDF program which achieved planetary motion of inner rod is compiled and numerical simulation for power-law fluid flow in eccentric annulus is achieved with application of dynamic mesh. Influence on velocity distribution, secondary flow, moment of inner tube and pressure drop by rotation parameters of inner tube was calculated. The results show: Reynolds number Re=24.083~828.75; revolution of the inner tube make the speed core area of fluid in eccentric annulus rotate around the opposite direction of revolution. When the direction of rotation and revolution is opposite, the secondary flow is obvious. The moment of inner tube and pressure drop of fluid in eccentric annulus increase when considering revolution and rotation of the rod.
