“…A few of these include the injection of gaseous fuel jets in a natural gas engine [1,2] or a supersonic combustor [3,4], discharge of chimney gases into the atmosphere [5,6], and thrust control of rockets and V/STOL aircraft via jets [7,8]. In most of these applications, an overall control of the fluid mechanics of the flow is required to improve the quality of the end process.…”

A highly underexpanded jet with a nozzle pressure ratio of 5.60 is excited simultaneously by the inherent characteristic frequencies in the steady jet of 14.569 kHz, 37.086 kHz, and 45.695 kHz as well as other two reference frequencies of 1.0 kHz and 40.0 kHz. The flow characteristic of the excited jets is revealed by comparing to the steady jet using large eddy simulation technique. For low-frequency excitation ( f e = 1.0 kHz), the flow and acoustic fields of the forcing jet are similar with the steady jet. However, when the jet is excited by high frequencies, the acoustic source moves to the nozzle exit, and the jet potential core together with the near-field shocks oscillate periodically at the excitation frequency. The excitation at f e = 1.0 kHz increases the mixing area since y/D = 24 from the nozzle exit, which is contrary to the effect of other high frequencies that enhances the mixing in the near-field region but decreases the mixing area since y/D = 18. The peak frequency of the excited jets generally becomes identical to the excitation frequency once being excited, except the f e = 1.0 kHz and f e = 40.0 kHz jets. High-order harmonics of the dominant frequency are observed in the pressure spectrum of jets excited by high frequencies, and the dominant mode turns into the axisymmetric mode from the original helical one accordingly. In particular, forcing the jet with the axisymmetric mode of f e = 14.569 kHz provides the fewest shock cells but the largest amplitude in shock oscillation, the most harmonics in the spectrum, and the largest mixing area within 8 ≤ y/D ≤ 12.
