摘要：
A random computational method was developed based on the hexagonal 7-bit Lattice Boltzmann plasma jet model using the acceleration equation for single particle. It made possible the simulation of the procedure of powder particles moving in plasma jet. The simulation result showed the whole process by animation. It indicated that the reduction of the diameter of powder spout of the increase of powder particles diameter would increase the availability ratio of the powder under the circumstance of the same plasma jet. The increase of powder particles diameter would lead to the reduction of the velocity of the particles. Higher powder velocity depended on the proper spray distance.
