The unsteady flow oscillation caused by the wake vortices generated from a number of objects is a meaningful theme for the fluid dynamics and aeroacoustics. The discrete vortex method has been used for a variety of incompressible high Reynolds number flows as a simple numerical simulation method, and this method has a merit in a point of easy treating for wake vortices. So discrete vortex method is often used for cascades flow, but it has a difficulty in directly applying for stator-rotor interaction because it could cause a locally unnatural flow by the interaction between wake vortices and bounded vortices expressing surfaces of objects. In this paper a suitable method using a sub-element method is applied not to spoil the basic algorithm and essential merit of the discrete vortex method and an investigation the basic mechanism of the interaction between stator and rotor is performed.
