In this paper, the Chimera method with the Schwarz algorithm which is one of overlapping domain decomposition methods is applied for a flow around a rotating body. The incompressible Navier-Stokes equations expressed in a non inertial frame of reference are used for the governing equations. The implicit scheme with accuracy of the second order is used for time discretization. The mixed finite element formulation with the iso-P2 P1/P1 elements for velocity and pressure elements is used for spatial discretization. For a numerical example, two dimensional analysis of a flow around a ellipse cylinder which rotates uniformly in a uniform flow was performed, the validity of the present technique was verified and the characteristics of the flow were considered.
