Abstract
This paper describes that an experimental study is performed to reveal the effects of an acoustic forcing frequency on flow characteristics in a plane jet. Active control of a planar jet has been attempt using a sinusoidal excitation blowing and sucking at the nozzle exit. The turbulent intensity of excitation is set at 2% of the jet velocity, the frequency of excitation is changed from 50 to 900 Hz and jet velocity is changed from 10 to 30 m/s. The hot-wire measurements directly provide phase averaged flow fields and they illustrate appearance of the jet fluttering.
