A 3D numerical method combined with the chimera grid and dynamic grid for splving Navier-Stokes equation is developed in this study. An upwind finite volume scheme with 4-stages Runge-Kutta method is used. The grid system is divided into main-grid and sub-grid systems. Informations transferred between the main and sub grid systems utilize solutions in the regions of overlap. All the overlap regions can not be too close to each other, otherwise interpolation will be difficult to calculate. Two tests: laminar flat plate boundary layer and MACA0012 pitching airfoil flowfield are used to verify the accuracy. Finally, 3D moving circular cylinder flowfields are studied.
