The operating principle of ultrasonic humidification

The principle of ultrasonic humidification is based on the superimposition of two effects:

1. Cavitation bubble implosion
The change in amplitude of the oscillator gives rise to powerful water hammers that release tiny cavitation bubbles. The implosion of the bubbles on the surface emits tiny water aerosols into the ambient air.

2. Capillary wave theory
The ultrasonic oscillators generate regularly formed Rayleigh surface waves in the water tank. Minute water aerosols are also emitted into the ambient air on the crests of these waves.

By superimposing these two effects, the use of ultrasonic humidifiers enables a homogeneous aerosol mist to be produced with minimal energy consumption!
