Abstract：To enhance the hydrodynamic performance and rust-removal eficiency of the UHP water jet rotary sprayers，a novel layout optimization strategy was proposed based on the PSO algorithm. The sweep impinging trajectory，accumulative impinging-duration，and self-rotary models were successively established based ona fully motion characteristics analysis of the rotary sprayers.The self-rotary model revealed the influences of nozle spatial layout on rotational speed and provided a theoretical basis fordetermining the attack angle.By regarding the uniformity of water jet impinging energy distribution and the sweep impinging width as evaluation criteria，a bi-objective optimization model was established. Then，the optimal spatial layouts of the nozzles were obtained via PSO algorithm，and the corresponding attack angles were derived from the self-rotary model. Finally，an actual optimization experiment was conducted using a rod-like shape 16-nozzle rotary sprayer commonly adopted in a shipyard of Zhejiang. Results show that the optimized design improves the uniformity of sweep impinging energy distribution by 22.81% and increases rust-removal eficiency by approximately 11.2% ：
