Abstract: The present disclosure provides a parameter design and numerical simulation method for jet trencher nozzle, comprising the following steps: S1. designing parameters of nozzle; S2. selecting the parameters of nozzle; S3. establishing a geometric model; S4. setting boundary conditions and delineating grids; S5. performing numerical simulation using Flow-3D; and S6. performing results 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.
