Abstract
The self-excited oscillation generated by two opposing planar jets is investigated experimentally. Strong flow oscillations resulting in intense acoustic tone generation are observed for wide ranges of jet flow velocity and distance between the opposing jet exits. A study of phase-locked particle image velocimetry (PIV) complemented with sound measurements is performed to clarify the self-excitation mechanism and the oscillation pattern(s) of the opposing jets.
