Abstract

In this paper, the structure optimization design of the nozzle of an explosive destruction device is carried out. The VOF model in Fluent software is used to simulate the nozzle. According to the structural characteristics of the nozzle, an axisymetrical two-dimensional geometric model is established for the nozzle and the external jet area, and the mesh is divided and encrypted. The computational fluid dynamics method is used to simulate the velocity and pressure of the jet flow field. The influence of straight and cone-straight nozzle on the velocity field and pressure field of water jet are compared and analyzed.The results show that the speed of the conical-straight nozzle with shrinkage section is relatively concentrated, less divergence, and the length of the core jet region is longer, the water jet energy loss is smaller, the penetration is stronger, the jet concentration and stability are relatively good.
