摘　　要：In order to improve the efficiency as well the adaptability and operability of traditional devices used to dredge drainage pipelines a new design is presented here,obtained by matching the structural specifications of a drainage pipeline with the working principle of a high-pressure water jet(HPWJ).To effectively improve the water jet nozzle performances,the nozzle’s structural parameters of the proposed device have been analyzed through Computational fluid dynamics(CFD)simulation.The corresponding behavior of the fluids inside and outside the selfrotational nozzle has been numerically simulated.The final design for the nozzle has been optimized taking into account such results.
