초록

Substantial alteration of the flow conditions in a fluid stream are effected by the application of controlled disturbances to the boundary of or within the stream by one or more piezoelectric actuators. The actuators have resonance frequencies substantially in excess of the unstable frequencies of the stream. The actuators are energized by carrier signals at the resonance frequencies of the actuators, which carrier signals have been modulated at the desired unstable frequency of the stream.

대표
청구항

A method for altering the characteristics of a fluid stream flow having unstable flow frequencies, the method comprising the application of controlled disturbances to the flow with a piezoelectric actuator having supplied thereto a carrier signal having a frequency substantially equivalent to the resonance frequency of the actuator and substantially higher than the unstable frequencies of the flow while modulating said carrier signal at a frequency to which the flow is unstable.
