Propagation Characteristics of Multi-Frequency Arc-Shaped Flat-Plate Ultrasound in Xanthan Gum Viscous Systems and Its Influence on Rheological Properties.

ABSTRACT: The solubility and rheological properties of high-molecular-weight xanthan gum (XG) are crucial to its functional performance and determine its applications. Ultrasound modifies these properties mainly by altering acoustic propagation in viscous systems, which depends strongly on concentration and frequency mode. In this work, the propagation behavior of three frequency modes (33 kHz mono-frequency, 20-40 kHz dual-frequency, and 20-50-68 kHz triple-frequency) of arc-shaped flat-plate ultrasound was systematically investigated in XG solutions, as well as their effects on solubility and rheological properties. Results showed that multi-frequency ultrasound generated stronger and more uniform acoustic fields, maintaining higher space peak temporal peak acoustic intensity (I_SPTP) ov
