What is Experimental Study of the Acoustic Pressure Distribution in a Sonochemical Reactor about?

## Abstract The work is devoted to an experimental study of the main parameters of the acoustic flow that occurs in a liquid under the influence of an ultrasound source (US) with a frequency of 1.7 MHz. To study the type of emerging currents, the method of tracer and fluorescence imaging was used; the distribution of relative acoustic pressure was found using a vibration sensor; to measure the intensity of cavitation events, thermocouple measurements were used. Experiments have shown that an increase in the concentration of the NaCl salt in the water solution reduces the intensity of vibrations when the sensor is removed from the ultrasonic source. The maximum intensity of cavitation events also changes its position, moving to the area near the ultrasonic source. Thus, the effect of an increase in the salt concentration on the type of flow in a sonochemical reactor was noted, which was also experimentally recorded in the work using light-reflecting particles.
