Abstract

Simulation on velocity field of gas-solid flow in the abrasive air jet nozzle was studied by the computed fluid dynamics(CFD) software. The velocity field of the two-phase flow in the abrasive air jet nozzle can be obtained by means of simulation. The effect of the nozzle diameter on the velocity field shows that the velocity field in the nozzle with a smaller diameter is more well-distributed. The velocity distribution along the nozzle axis and the radial direction of the nozzle outlet was also simulated.
