Simulation and optimization of acoustic streaming field in bath‐type sonoreactors considering cavitation attenuation

Abstract High‐intensity ultrasound induces significant acoustic flow in liquids, but cavitation‐caused attenuation alters its characteristics. Most existing studies use linear models neglecting bubble nonlinearity, causing discrepancies. This paper investigates a bath‐type sonoreactor with a nonlinear model accounting for cavitation. The 3D acoustic streaming field is reconstructed numerically. PIV experiments verify the results. Drive power is positively correlated with streaming intensity; optimal flow is at 90 W. Reactor width affects lateral jet coverage; 375 mm width at 90 W gives superior mixing. Liquid level modulates pressure gradient; best flow is at 4–5 wavelengths in a 300 mm‐wide reactor. The optimal parameter combo is 90 W, 6 wavelengths width, and 5 wavelengths level.
