This study explores the innovative use of ultrasonic technology in process intensification using COMSOL multi-physics simulation. It investigates effects parameters like power (60–320 W), frequency (20–40 kHz), and horn diameter (8–30 mm) on sound-field distribution, fluid dynamics, cavitation. The optimal for uniformity cavitation was found to be 28 kHz, with a maximum flow velocity 0.352 mm/s. Increasing from 60 320 W raised sound pressure 1.05 × 105 2.43 106 Pa area volume fraction 2% 17%. significantly influences wave diffusion energy larger diameters providing higher density covering areas increased rates. Using multiple ultrasound sources enhances acoustic fields over area. simulation model's feasibility confirmed through ultrasonic-enhanced ZnO crushing experiments varying diameters. research provides scientific basis optimizing intensification, advancing theories ultrasound-enhanced mass transfer chemical reaction efficiency, holds potential improving greening efficiency hydrometallurgical technologies.

In industrial production and scientific research, ultrasonic cavitation technology, with its outstanding physical chemical processing capabilities, has been widely applied in fields such as material surface modification, synthesis, biotechnology, becoming a focal point of research application. This article delves into the effects different frequencies on outcomes through combined use numerical simulation, fluorescence analysis, high-speed photography, specifically analyzing quantitative improvement mechanical properties TC17 titanium alloy under at 20 kHz, 30 40 kHz. The study found that an frequency maximum expansion radius bubbles can reach 51.4 μm, 8.6 times their initial radius. Correspondingly, intensity peak area also increased to 402.8 28104, significantly above baseline level. Moreover, after modification by cavitation, original machining marks became fainter, emergence new, uniformly distributed microfeatures. microhardness from 373.7 Hv 383.84 Hv, 396.62 414.06 10.8 %. At same time, height difference roughness decreased (to 3.168 μm 0.61 respectively), reductions reaching 45.1 % 42.4 %, indicating significant quality. Notably, there is negative correlation between frequency, suggesting decrease increases. not only reveals relationship but provides solid basis practical guidance for application technology engineering, signifying technology's potential broad future.
