A sting oscillator that produces sonic oscillations from a steady state fluid flow. A rigid sting is mounted concentrically within a resonant cavity in either a three-dimensional conical form or a two-dimensional wedge flow form. Fluid vortices shed from the sting cause the cavity to trigger into oscillation, creating alternating pressure waves that are dispersed in all directions. The oscillatory pressure waves can be transduced into useful electrical or mechanical power to drive any desired external device. The high pressure, large volume input flow capabilities of the sting oscillator provides power outputs heretofore unobtainable with fluidic devices. Several possible embodiments of transducers coupled with the device of the present invention are presented herein.
