“…The rapid development of dredging robotics technology for drainage pipelines is mainly divided into two categories: pipeline detection robots which perform a series of pipeline inspection and maintenance operations under the control of the operator [8][9][10], and pipeline dredging robots, in which dredging function is performed by installing various dredging devices on pipeline dredging robots [11][12][13][14]. So far, researchers have generally focused on pipeline detection robots [15][16][17].…”

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.
