Low level sinusoidal jet excitation is observed to significantly affect structural and mixing characteristics for transverse jets with convectively unstable jet shear layers under unforced conditions. Such excitation, especially in a frequency range close to the fundamental, is found to attenuate the cross-sectional asymmetry naturally occurring in such unforced jets. There is also improved molecular mixing for excited jets with more symmetric cross sections. Yet when the  ...  sinusoidal jet excitation barely affects jet structure or mixing, even with a very high forcing amplitude and wider range of forcing frequencies. Different forcing methods, e.g., creating alternative temporal waveforms for jet excitation, are clearly required to control the structural and mixing characteristics of transverse jets based on these differing instabilities.
