Controlling Hydrodynamic Generator Emission Intensity at the Edge Tone Frequency

The paper considers the possibility of increasing the efficiency of flow hydrodynamic elastic waves generator being used to intensify chemical and physical processes. To increase the emission intensity at the edge tone frequency, it is suggested to use Helmholtz resonator. The possibility to control pressure differential created by a resonator as a result of the liquid flow velocity at the ring-spray nozzle of the flow generator is experimentally confirmed. For maintaining maximum amplitude values of the genevelocityd oscillations, the coalescence of the edge tone frequency with Helmholtz resonator frequency is necessary. With this purpose, extremal automatic control system is suggested.
