Abstract: Simulation of the velocity field of solid-liquid flow inside and outside the abrasive waterjet (AWJ) nozzle is studied by computational fluid dynamics (CFD). The flow field of the flow inside and outside the AWJ nozzle is obtained. The simulation results indicate that there is a sudden increase in the jet velocity near the corner inside the nozzle, and then it remains steady in the focus tube. When AWJ ejects from nozzle, the diffusion happens and the velocity of the flow is slowly decaying. The simulation results also indicate that AWJ flow field is affected by the impact angle on the target. The higher impact angle becomes, the more obvious effect on the flow field is. The simulation results show that there are a large eddy and negative pressure zone in the flow field when AWJ impacts on the wall, and which will help to entrainment removal of the material.
