Abstract:
The mean-square pressure far downstream in the jet considered as an index of trapped energy is determined for a two-dimensional source in a two-dimensional jet of infinite length. Jets having shear layer boundaries and velocity discontinuity boundaries are considered. Results from the particular examples chosen suggest that in certain frequency bands this trapped energy in the infinitely long jet is significant. Author
