AI Technical Summary
The existing jet oscillators have problems such as high hydraulic loss, low oscillation frequency, large friction loss and difficulty in controlling waveforms in the generation of micro bubbles, which limits their widespread use in industrial applications.
A new Desai-Zimmerman (DZFO) jet oscillator is designed, using a new switching mode combining acoustic cavity and shunt, which achieves higher oscillation frequency and lower friction losses through acoustic resonance mode, and can generate controllable waveforms.
Achieve higher oscillation frequencies (up to 20kHz), lower friction losses, enable smaller bubbles to be generated and amplitude optimization is achieved without excretion, suitable for a wider range of microbubble generation applications.
