WHAT IS ULTRASOUND TECHNOLOGY?

Ultrasound refers to sound waves with frequencies exceeding 20 kiloHertz (kHz) of the sonic spectrum, which is the upper limit audible to humans. 

The ultrasonic transducer is the electronic device used to create these sound waves, by means of converting electrical energy into sound energy (pressure).

Pressure fields created by the ultrasounds can be applied to a solid, liquid or gas medium, to alternately compress and stretch the molecular structure of the medium. Nowadays, ultrasound is used in many different sectors and applications: to, such as for the detection of objects and measurement of distances in medical imaging, or in industry for cleaning, mixing, and accelerating chemical processes, among other applications.

HOW ACOUSTIC CAVITATION WORKS?

When HPU is applied to a liquid, it generates acoustic fields (pressure fields) inducing pressure variations in the medium, subjected to mechanical forces that create alternating cycles of low-pressure (depression) and high-pressure waves (compression), causing the formation of millions of small vacuum bubbles. Two possible events may occur:

· The bubbles oscillate around their equilibrium position over several compression/rarefaction cycles, merge with other small bubbles and rise to the surface. These type of bubbles are called ‘stable cavitation bubbles’.

·The bubbles keep growing over a 1 – 4 compression/rarefaction cycles, until they reach their critical size. Finally, they collapse and violently implode, transforming the shock waves into effective mechanical effects. The implosion results in intense shear forces in the liquid media, and very high local pressure and temperature (5,000 ºC and 500 bar) within the bubble, whilst the overall temperature and pressure of the bulk media remains at ambient conditions. These type of bubbles are called ‘transient cavitation bubbles’. This phenomena is called acoustic cavitation.

Cavitation also results in the generation of local turbulence and liquid micro-circulation, enhancing the rates of transport processes. Thus ultrasound-induced acoustic cavitation can be used to perform chemical or mechanical processes at ambient temperatures, and finds widespread applications in chemistry, industry, materials, life sciences, and medicine.
