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