EXPERIMENTAL STUDY OF ACOUSTIC FLOWS IN A FOCUSED ULTRASOUND FIELD

摘要

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 method can be effectively used for rapid diagnostics of a spatially inhomogeneous acoustic field.
