Simulation of the flow field of the gas-liquid-solid three-phase flow outside the abrasive water jet rectangle nozzle and ellipse nozzle is studied by the computed fluid dynamic software-fluent, and the velocity field of the three-phase flow is obtained. The simulation result expresses that the flow is expanded when it is out of the nozzle; the velocity of the flow is the highest at the axis, which comes down by its side, the velocity of the flow is high at the beginning then it is decreased because the flow is resisted by the air; the shape of the jet at the start is closed to the geometry of the nozzle, then it is rounded in the external area; the velocity field outside the ellipse nozzle is distributed evenly around the center. By plotting the velocity field of the rectangle nozzle and the ellipse nozzle in the Y-Z section, it is expressed that the changing range of velocity is enlarged with the increasing of distance offset the nozzle.
