The purpose of this study is to clarify the effects of periodic disturbance with amplitude or frequency modulation on the turbulence characteristics in the wake of flat parallel plates. The periodicity of the wake without reverse flow like the flat plate wake is sensitive to disturbance. We are trying to control the turbulence characteristics of the wake using various disturbance method. In this study, the amplitude or frequency of the periodic disturbance signal based on the prominent frequency in the wake was modulated. As a result, it was found that the spectrum distribution and turbulence characteristics of the wake change on the modulation frequency.
