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)*** corresponding behavior of the fluids inside and outside the selfrotational nozzle has been numerically *** final design for the nozzle has been optimized taking into account such results.
