PARAMETER DESIGN AND NUMERICAL SIMULATION METHOD FOR JET TRENCHER NOZZLE

摘要

Disclosed in the present invention is a parameter design and numerical simulation method for a jet trencher nozzle. The method is characterized in comprising the following steps: S1, designing parameters of a nozzle; S2, selecting the parameters of the nozzle; S3, establishing a geometric model; S4, setting a boundary condition and delineating a grid; S5, performing numerical simulation using Flow-3D; and S6, performing result processing and analysis. According to the present invention, the whole process of nozzle flushing and ground breaking can be simulated, the size of the cross-section of the flushing trench is measured, and by analyzing the obtained result, the reasonability of nozzle radius parameter design can be verified, and a certain reference is provided for design of inclination angle parameters.
