Abstract

Investigating the conveying and mixing characteristics of high-viscosity fluids in an inclined flow channel under the excitation of acoustic frequency vibrations using computational fluid dynamics (CFD) methods. As the intensity of the acoustic vibration excitation increases, the free surface of the liquid transitions from generating Faraday waves to generating disordered jets. Continued increase in the amplitude leads to the liquid filling most of the vessel space, causing a blockage. However, slowly increasing the amplitude alleviates the blockage phenomenon. When high-viscosity materials are subjected to high-intensity acoustic vibration, the flow field is dominated by shear flow, which is accompanied by efficient stretching and folding. Changing the amplitude or frequency alone can cause blockage, and increasing the frequency of vibration excitation alone will not alleviate the blockage. Instead, increasing the amplitude can generate more mixing-promoting reflux, effectively relieving blockage while maintaining stable conveying capacity.
