Abstract: | In this study,the distribution behavior of the particle flow field in cold gas dynamic spraying(CGDS)was simulated through the computational fluid dynamics(CFD)method.Traces of the particles with different diameters in the gas flow field were analyzed,and effects of flat and sphere substrates on the particle tracks were also compared.Simulation results indicate that different escaping directions of particles flow with the two substrates.These investigations gave instructions on how to design the powder recovery and dusting machines in a CGDS system. |
