Abstract : The problem of a submerged incompressible two-dimensional jet pivotally oscillated at its base was studied analytically and experimentally. The analysis, corroborated by experiment, shows that the phase velocity of the propagating disturbances is much less than the jet velocity of for most frequencies of interest. Futher, the amplitudes grow faster than linearly, with the rate dependent on frequency. These results have considerable implications for the dynamics and noise generation of fluidic amplifiers. All of the desired boundary conditions have not yet been accommodated analytically, and the experiment needs a refined method for dyeing the jet. (Author)
