Characterization of Electromagnetic Field Intensity Through Random Distributions of Bubbles Induced by Acoustic Cavitation

Acoustic cavitation is a complex phenomenon to study and model due to the effects it produces in liquid media, mainly the generation of bubbles. Among the complexities are the number of bubbles generated, their location, and their size. For this reason, it is proposed to use an optical medium such as light in the form of an electromagnetic field to quantify the level of cavitation present in a liquid medium. For this, a model is required to represent what happens when cavitation is generated, so first, a matrix that randomly represented the complex parameters of the bubbles generated by cavitation (quantity, size, and position) was programmed. In this model the study of the intensity of the electromagnetic field through a medium with water and bubbles in different random distributions was performed. Analyzing the relationship found between the reduction in the intensity of an electromagnetic field because the reflection, refraction, and absorption of the waves with cavitation randomly induced bubbles, regardless of their diminished size it was found a reduction in the field intensity of 5.03% and 6.87% depending on the size and number of bubbles generated. This study was the first step to approach a new optical technique to quantify the level of acoustic cavitation.
