Short summary

This study uses a relatively novel optimization system to optimize the structure of a self-excited oscillating nozzle. The study identifies inlet radius, lower-nozzle diameter, and cavity length as key variables (combined impact >87 %); achieves a 77.39 % improvement in overall cleaning efficiency through global optimization; and explains the flow field evolution mechanism.
