The DNSs of the incompressible flows around a circular cylinder are performed by using the Cartesian grid approach with virtual boundary method. In the virtual boundary method, the body surface is expressed by a set of plural points, and the velocity components on virtual boundary are feedbacked to the momentum equations as the additional forcing terms. As a validation of this method, the steady flows around a circular cylinder are computed in order to investigate the dependence of virtual boundary points on flow characteristics. Then, this method is applied to the unsteady flows. The results show that the present method is very promising for the DNSs of the incompressible complicated flow.
