In view of the incomplete cleaning of the ballast water filter,from the perspective of the cleaning effect of the ballast water filter suction nozzle,the influence of the internal diameter of different suction nozzles and the conical structure of the suction nozzle on the internal flow field is analyzed.The pressure field distribu-tion of different structural forms of the suction nozzle is obtained by Fluent analysis method.It is found that the pressure field distribution of the A-type suction nozzle is better and the pressure loss is smaller,and the pressure loss of other types is larger.At the same time,according to the analysis results,the optimized structure is ob-tained,and the pressure difference loss before and after the A-type suction nozzle will be 0.Through experimen-tal verification,the experimental results are basically consistent with the simulation analysis results,which pro-vides effective suction nozzle data support for the subsequent ballast water filter in effective cleaning.
