Ultrasonic cavitation in water produced by a Barbell Horn with a 35 mm tip diameter

does the water heat up?

@pixelspring Yes, about 1 kW of acoustic power is going into the water and converts into heat. For practical applications, temperature control is needed. For example, in flow-through applications a cooling jacket on the reactor chamber or a heat exchanger would commonly be used.

@dediamada2008 No, there will just be "wind" hitting the surface. For cavitation to occur, the Barbell horn must be immersed

If the Barbell Horn is placed above water surface. Will cavitation work?
