Ultrasonic Frequency at Aqueous Washing Line

Question invalid.

why invalid?

What washing liquid are you using and are you using a front loading washing machine?

I have an 167li Tank with DI water and .20% Triton-X Surfactant. Its is an ultrasonic washing machine with washing jig being load and unload withn 3mins. Followed by cascading rinsing system.

Most probably you will get an interference between the 2 waves which will generate a third frequency function of the difference between the 2. This interference will generate a field of peaks and valleys (speaking of the amplitudes). This pattern depends on phase shift between the 2 generators. Depending on the nature of the fluid and the walls the reflected waves will also play a role in the pattern generation.

Assuming you are talking of an ultrasonic bath, You will have the main frequency components 28 kHz and 40kHz together with their mixed frequencies...

28 +/- 48 x n where n= 1.2.3.4.5.6.......

And then you will have multiples of these frequencies ....

28 x m +/- 48 x n where n = 1.2.3.4.5.6 and m= .....6.5.4.3.2.1

Have fun working them out - John.

Also, as the wavefronts travel in opposite directions, there will be the difference frequencies. 12kHz will be one of them.

Harmonics are always smaller than the incoming waveforms, unless there is some kind of resonance within the washing machine. Try a lower spin speed.

wow, i think i need some time to figure this out...

Thanks anyway for all the replies...

you will still have both frequencies. and as already stated you will have harmonics of both individually and together. The two frequencies will each cause cavitation bubbles at their own freq. the low freq. causing larger bubbles that are more aggressive. The larger the cavitation bubbles the more energy that is released when they implode causing a plasma jet that performs the cleaning action.

Cleaning at one frequency for an extended period can cause the part being cleaned to oscillate at that frequency causing breakage to some materials.
