Experimental study of acoustic flowsin a focused ultrasound field

The development and structure of steady-state acoustic flows in the focal region of a spherical ultrasonic concentrator is first studied using the particle image velocimetry (PIV ) method in order to improve the technology of rapid growth of salt single crystals. By comparing the results of rheological and acoustic measurements, it is shown that the PIV
