Abstract
A flowfield including local internal flow is difficult to investigate in both experiment and numerical simulation, even though such flow is significant from the point of engineering, for instance flap and slat of a wing. Recently, this kind of flow can be treated by numerical simulation by using high performance computer with large scaled computational grid. However, the complicated geometry consisting of a number of parts with close distance has difficulty still now especially for the grid generation. In the present study, Cartesian grid method is employed for automatic grid generation for the complex geometry with utilizing cut cell method. The flow solver is going to be applied to the flowfield of flat plates in the vicinity of the wall to capture the flow interaction of the objects.
