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.
