In order to elucidate the enhancement mechanisms of turbulent flame propagation, it is indispensable to examine and clarify the detailed process of vortex-flame interaction. In this investigation the plane shear flow between two parallel walls in numerically simulated by using the discrete vortex method. Two parallel walls are set to stabilize discrete vortices. The effect of the acoustic excitation is replaced by small fluctuation of the flow velocity. while that of the volumetric expansion is expressed by the source on the flame front. In this paper the flame propagation behavior in the plane shear flow is numerically analyzed and compared with the experimental results. It is found that the calculated flame propagation velocities agree well with those experimentally measured.
