| Abstract Scope |
This study investigates the fundamental mechanisms of acoustic field-assisted material processing, focusing on the precise manipulation and aggregation of fine particles using audible frequency ranges. By applying controlled acoustic fields, acoustic radiation forces and acoustic streaming are utilized to drive particle transport and overcome Brownian motion. The interaction between the low-frequency acoustic waves and the medium enhances the collision frequency of fine particles, leading to accelerated aggregation processes without reliance on ultrasonic cavitation. Systematic experiments and in situ observations demonstrate how field parameters, such as specific audible frequencies and acoustic energy density, dictate the spatial distribution and structural morphology of the resulting aggregates. These experimental findings provide a scalable and energy-efficient pathway for controlling particle-phase transformations and refining microstructures in field-assisted engineering applications, bridging the gap between fundamental low-frequency acoustic-matter interactions and advanced manufacturing technologies. |
