This sound wave do not heard is called ultrasonic wave.
Ultrasonic wave can be propagated usually in a manner of longitudinal wave in elastic fluid, be a kind of mode of propagation of energy, feature
It is supersonic frequency height, wavelength is short, has good beam and directionality along straightline propagation in certain distance.
If gassy in container or in pipeline, when its internal pressure is more than external pressure, due to interior external pressure
Difference is larger, once container has leakage hole, gas will be gone out from leakage hole.When orifice sizes are smaller and Reynolds number is higher, flush gas
Body will form turbulent flow, and turbulent flow can generate the sound wave of certain frequency near leakage hole.Utilize this feature of sound wave, you can judge
Go out correct leak position, therefore supersonic reflectoscope occur.
