Investigating the conveying and mixing characteristics of high‐viscosity fluids in an inclined flow channel under the excitation of acoustic vibration using computational fluid dynamics 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.

声振动激励下高粘度物料的连续输送与混合特性

利用计算流体动力学方法研究声振动激励下高粘度流体在倾斜流道中的输送和混合特性。随着声振动激励强度的增加，液体的自由表面从产生法拉第波转变为产生无序射流。振幅的持续增加导致液体充满大部分容器空间，导致堵塞。然而，缓慢增加振幅可以缓解堵塞现象。当高粘度材料受到高强度声振动时，流场以剪切流为主，并伴有高效的拉伸和折叠。单独改变振幅或频率会导致堵塞，而单独增加振动激励的频率并不能缓解堵塞。相反，增大振幅可以产生更多的促进混合回流，有效缓解堵塞，同时保持稳定的输送能力。
